Handel- Where'er You Walk
Brahms Intermezzo in A major
This piece is in composite ternary form. It starts out in A major and at first has four symmetrical phrases that seem to make up a phrase group more than periods of some sort. After the phrases, there is a rather sudden modulation. The A section continues until the pickup to bar 49. The line before this contains an extra terminary phrase/cadential extension and then we have the B section. B is in binary form. There is a drastic drop in tempo in bar 57, along with a ritardando beforehand, switch to legato, and a dynamic marking of pianissimo, all of which set this section apart from the others. This lasts until bar 64 when it returns to a part similar to the one we were first introduced to in the B section as can be seen by the left hand's arpeggiations. The A section returns in bar 76 after a ritardando and decrescendo, and then there is a change in dynamic. It begins with the original motive from the beginning of the first A section but then changes into having more of a developmental function.
Brahms Intermezzo in A Major
Brahms: Intermezzo in A major, Op. 118, No. 2
Well, since everyone and their mom decided to do “where’re you walk” …. I thought I would be different and try this piece that I probably won’t get close to right. So…here we go…
The A section starts off in A major. It starts of with four phrases that don’t really make up a period, but more likely a phrase group. At the end of the forth phrase I don’t think it has modulated yet, and ends with another HC in A major. At the end of measure 16 I feel it modulate and all the natural signs help out, but I’m not sure which key it goes to. This also feels like it could be a “new” section in the A section (possibly binary). Possibly E major, but I’m confused on the C#EG chord…Then I feel it shift again not to much later in measure 20...its keeps moving and I’m not really sure all the keys it covers. The A section starts again in measure 28-29 and ends in measure 48 with a PAC in A Major.
Measure 49 takes the piece into the B section. The tempo is put back in place, and the B section last until measure 76. Well…the beginning of the B section seems to arpeggiate and focus around the F# making me think that it has changed to the minor of A major…F# minor…
The A section ends up returning in measure 76 ending the piece on a PAC in A major….
I believe that this composite ternary because of the A section feeling somewhat binary..
Ahhhhhhhhhhhhhh…I just need to stop this music thing…no good….Obviously music doesn’t want to pick me!!!
Brahms Intermezzo in A major
G.F. Handel
Brahms: Intermezzo in A Major
At m. 17 we're back in A and there's an IAC at m. 20. This is our b section. It's tonally ambiguous and lasts for 12 measures. The chords don't seem to make any sense as to declare a key.
At 29, it seems like we're back at the A section (sigh of relief). At first is appears to be the same, but we'll notice that both the melody and the texture (especially in the left hand) is somewhat different. We end on a nice PAC in the key of A Major.
The B section starts at m. 49 and we're in f# minor. After the first 4 measures there is a HC and then a transition to the key of c* major (the dominant) for a PAC in m. 56 and continuing on for a while in the b section. there's a PAC at m. 60 and another at 64. The original melody from the start is b is being used, but has been transposed to the dominant. At 65 we're back in f# and there's a HC at m. 68. I feel like there's either a HC at m. 72 or that this next 8 bars is a transitory phrase to get us back to the recapitulation of the A section.
A starts up again at m. 76. We get the a once, followed by the b, and then with our a again. Obvious binary. I love it. All this is the same as the first time with four bar phrases and what not.
hmm.. i think i'm sleepy now....that means i'm done!!
Comments not working I think
Here is what I said to Liz:
So that would make A closed and B open? Isn't that pretty typical of Da Capo Arias? That's all I've seen them do so far.
Here is what I wrote to Mr. Luxury Yacht: This is a real question: um, can the trio be rounded if it begins in F Major and ends in the minor? Can any binary still be rounded if ends in the parallel major or minor?
Handel
The piece is written in Bb Major in simple ternary form. The A section (to M. 19) is an asymmetrical, contrasting period. The first phrase ends on a HC at M. 7. The second phrase includes a nice cadenza, which seems to me like a sort of cadential extension from M. 12 to M. 16 when we finally reach an IAC. There is a three measure repetition of part of the first phrase, which ends in a PAC.
The B section is less tonally stable – it starts in g minor and ends in c minor. There aren’t many clear cadences in the B section, however I did notice that we hit a AC in M. 24, and interpolation is used to tack on another AC at M. 26.
The A section is repeated, exactly the same as the first time. Typical Da Capo aria. This piece is simple ternary form because the A sections do not have other binary or ternary forms within them.

Where'er you walk - Handel
Intermezzo in A Major - Brahms Op. 118, no 2
It is a composite ternary form where A is closed, B is open, and A' is again closed.
A is a binary form, and honestly I'm torn as to rather it's rounded or simple. For you see, a' ends in the key of A Major, but it's last four bars--texture-wise--resemble much more nearly the b section, even though part of the original a motive are interspersed and even the return of a is signaled by a variation on the original theme, a' seems too different, and b is also longer with a transition of at least three measures. For a, we have a parallel progressive repeated period with symmetric four bar phrases. The first phrase ends on a half cadence in A, the second on an IAC in E, and then repeated. B lasts for eight measures and is highly tonally unstable. For instance, immediately after the E major chord ending the a section, we have a C major (chromatic mediant) chord which is then followed by a dimished built on a c sharp which resolves to a Dominant seventh built on E (the leading tone of the diminished going to the seventh of the dominant seventh) which resolves to I'm not quite sure what. This is in the fourth measure of b, and then we begin again with another four measures beginning in F major this time (moving up and adding energy like a good development). This second four measure phrase group ends on an E major chord and moves on into three measures of transition to arrive finally at a'. We seem to have the return of the original motive; however, in the third measure it changes direction and we have two repeated subphrases containing new expository material ending the first phrase on a sort of plagal cadence in its eigth measure. We commence the next phrase with a return to the high a, which reminisces of the original a, but does not quite come through. We have this time a four measure subphrase that highly resembles the original a, but a sense of authentic cadence is deprived us as the right hand ends on a d and g on the strong beat of the fourth measure. And so we move on to a rather sequential set of measures pausing again at a weak authentic cadence another four measures on at m42 and finally cadencing strongly at the end of another eight measures in A major(m48), thus making big A closed. You could see the cadence having occured right at m38 with the first weak PAC and the rest just being an extension on that original cadence. It certainly does have a winding down feel to it after that point, and there is no more return of the original a melody after that point.
Section B of the ternary form looks actually like a little, simple ternary form. To begin, a is in f minor and ends the first four measures with a quick HC and then in a following 4m contrasting phrase modulates to what I feel to be C# major and ends on a half cadence leading smoothly back to that original c# in the beginning B melody. Thus a of B is open. Then b of B moves into the dominant minor, so you get that nice sighing effect of the C# major half cadence resolving to the parallel minor. After four bars of the b, we have an IAC cadence on c#, further weakened because it is on the second beat of the measure. Then the phrase repeats and ends now on a PAC in c#. So we have a nice parallel, symmetric period for b. And b is closed. There is then a modified return of a, beginning again on the c#, only this time an octave lower. Again after four measures we end on a HC and then after another four we end on a PAC. I call this ternary because b is stable in its tonality and complete unto itself. Also there are no transitions.
Then at m73 we have a transition of four measures into the return of A. This transition ends on a suspension of the dominant of E with the E already lying in the bass. Here a only plays once before we enter into b and then the a' is the same as before.
So there you have it: composite ternary. A closed--simple binary?, B open (as it ended in c# minor the dominant of its starting f# minor) simple ternary, and A closed.
Everyone should listen to this, cause it's so pretty.
Beethoven: Sonata in F minor, Op. 2, No. 1, III
This piece is obviously in F minor. The first four bars end with an IAC in F minor, the second four bars with an IAC in the relative major Ab and the third four bars end with a PAC in Ab. There is a progression of stability in each but I have a hard time making any of them a period. After these three four bar phrases there is two bar extension to establish the key of Ab major. The second part of the A section modulates from Ab major to Bb flat major for a PAC in the sixth measure. The next four bars are an extension of the phrase with the exact material being repeated all four times. If you don't know the key by this point, you are a complete idiot! The next phrase is four bars long and modulates again to C major. The next phrase is eight bars long and works in sequence to get from C major back to F minor. Then after this the same extenstion from the first part of the A section followed by another two measure of V and i to make sure the listener knows the key. This could be considered a continuous rounded binary piece, but this is just the menuetto, there is still the trio left.
The trio does a direct modulation into F major. The first section of the trio consists of only one phrase that is ten bars long. There is a change in melody from right hand to left hand in measure 5 but it doesn't feel like cadence until the PAC in C major. The second section goes all sorts of crazy places due to the bass line sequence up for eight straight measure and once again contains only one phrase that is 15 bars long ending on a half cadence in F minor. Then the first part is repeated again but shortened to only eight bars and ends in a PAC in F minor. If this part were alone it would be a continuous rounded binary piece.
But since these pieces are together, they combine to form a piece in composite ternary form.
Handel
This is an example of simple ternary form. The A section is made up of an asymmetrical contrasting period. The first phrase cadences in measure 7 with a half cadence. The second phrase cadences on a PAC in Bb Major in measure 19. The next 3 measures can be considered a cadential extension that helps transition into the B section. The dynamic changes from piano to forte during the extension, which makes the piano B section even more effective and noticable. The A section is considered closed, because it ends in the original key of Bb Major.
The B section brings a change in tonality to the key of g minor. There isn't a strong tonal center here, and no real strong antecedent/consequent feeling, so I call it a phrase group. The B section ends on a PAC in the key of c minor. I consider this to be simple ternary form because the B section is harmonically dependent on the A section, and couldn't survive all by itself. There ya have it.
Handel where'er you walk
Brahms- Intermezzo in A Major
The A section is in binary form and begins in A major with a half cadence at measure 8. You could say this was a PAC, but I don't feel like it modulates til the next cadence at 16 when it really is a PAC in E major. The b section of the A starts at 17 and can only be described as a phrase group. Then we sort of have a "coda" type thing instead of a return to the a section from m. 38- 48.
The B section begins with a little introduction from m. 49-56. It appears to be in f sharp minor. When we get to the real B section it starts in F# major and uses a cannon-type motion to play around in different keys. Then in measure 65 the B section begins its transition back to A major and finished on a PAC in measure 76.
Then we are back to the A section which is much shorter this time. The song of course ends in a PAC in A major.
I was afraid to get really into this piece because it's sooooo complicated. If someone is looking for a piece to write a good LONG paper on, I suggest this one. I did my best! :-)
"Where E'er You Walk" from Semele by Handel
Mozart, String Quintet in G minor, K. 516
The A section of the piece is a continuous simple binary form. In part a, we have a 12 bar phrase group, punctuated by loud vertical attacks, juxtaposed next to the soft half cadences we hear in places. There is a hint of an IAC near the end. In the b part, the first 14 measures are one big phrase in my opinion, ending on an IAC. This phrase sequences up in the melody, building to the forte chords we found in the first part. After the vertical attacks, we conclude this section on our first PAC, with a common tone modulation transitioning us to the B section of the overall ternary form.
The B section is another continuous simple binary form modulated to the parallel key of G major. This section changes meter, and key, a stark contrast from the A sectionl. In the trio, notice the solo violin part. This section highlights the first violin, with the rest of the quintet accompaning. Filled with phrases ending in HC, this progressive part is a phrase group. The second part is similar to the previous part in the B section, however it is modulated to a minor, (I think). Again we see the soloistic first violin part, with the rest of the instruments filling out the harmonic progression. Notice how Mozart plays with the dominant and iv chords. Finally we end on a PAC in G major, and da capo back to the beginning for a literal repeat of the A section.
Handel-Were'er you walk
It seems to be in simple ternary form, just because it develops this A theme in Bb Major comprised of two assymetrical periods the first ending in m.7 on a half cadence, and the second ending in m.16 on an authentic cadence that at first was difficult for me to pinpoint as being perfect or imperfect but I hear it as perfect. There is a cadential extension after the authentic cadence which is followed by another PAC. Then the B section modulates clearly to G minor, the relative minor, giving a distinct, new flavor and independent idea to the piece. The B section also seems to be a bit tonally unstable and very open with emphasizes its independent nature even more. The A theme returns in the original key of Bb Major completing the cookie cutter "statement-contrast-restatement" format that is so typical of a ternary form. The da capo really gives that away, the Temko talks about the Baroque Da Capo Aria as being a prime example of simple ternary form with its three basic divisons.
handel from burkhart
the a section is an asymmetrical parallel period. the first phrase ends in meausre 7 in a half cadence (the V chord is tonicized--look at all those e naturals!) and the second phrase ends in measure 16 in a PAC in the original key of b flat, making this section tonally closed. there is kind of a cadential extension for 3 measures that ends in yet another PAC in measure 19.
the b section begins in measure 20. it changes key to the relative minor (g minor), but ends in a PAC in the key of c minor right before the return of the a section. the section feels more tonally open than the first, which is probably why the a section is revisited. this section also does not give the listener any particular structural feeling, which is why i think it can be called a phrase group.

Chopin Mazurka in A minor, Op. 17, No. 4
Schumann: Myrthen, Op. 25, No. 1, “Dedication”
I have heard this song many times in german diction, and it is fairly simple song, not too long. It is written in ternary form, ABA.
The A section last from M. 1-13, and is in the key of A-flat major. It stays in A-flat major for the whole A section and ends on a PAC in m. 13. It ends in the original key so it is closed, and I view it as a phrase group because the cadences are hard to hear….
The B section is very clearly show with many structural phenomena. There is a tonality change to the key of E major, change in dynamics, texture, and tempo. This B section is completely different from the A section. The arpeggiated chord accompaniment has changed to steady quarter note block chords. The vocal line seems to have less motion and more sustained. The B section last from M. 14-21, and ends on a HC. This next little phrase I believe functions more as a transitional section delivering us back into the A section.
The A section picks back up in measure 26, but doesn’t restate the original idea until measure 30. This whole A section is back in A-flat major and ends on a PAC with just the piano part adding sort of a cadential extension repeating what the vocal line just had...
Peasant Dance- Bartok
The B section is much softer and more accented than the A section, and it has a completely different feel and mood.The rhythm and the texture are also much different from the A section. There is a call and response kind of thing going on between the right hand and the left hand. There is then a 5 bar transition back to the A section. As far as I can tell, the B section is tonally open.
We then have the return of the A section, but it is differeny rhythmically and texturally than it was the first time. There are also embellishments added.
Thats it as near as I can tell... Id love to go over this one tomorrow so I could figure out what is happening with all the key changes...

CHOPIN- Prelude n F# Major Op. 28 No.13
At first it was a little hard differenciating between a phrase group or a double parallel period for the opening of the A theme. I think I have been so used to binary forms that I immediately wanted to call this an open continuous binary just by looking at the first period. However, it is actually a pretty clear ternary form. I ended up deciding that it had to be a double parallel period with asymmetrical phrases both ending on half cadences. There is a modulation to the dominant, and its hard for me to pinpoint exactly where it occurs but listening to the piece, it is definately something that you can hear. Over the course of the period, I felt like the rhythm was really played with, stretched, pulled and molded which was kind of a cool thing. The second half of the period doesn't feel as tonally sound to me as the opening, it ends on a strange cadence that gives an uneasy tone to the piece. The section ends though with what seems to be a cadential extension starting in mm. 18-19 which really gives a sense of finalization and was more tonally satisfying.
The B section is somewhat reminiscent of the A theme as far as a few rhythmic and harmonic motives go, and I was just happy to see it end on a PAC back in F# minor after the previous stint of harmonic instability.
The return of the A theme, the third and final section of the piece brings about a similar period structure, however, this time the periods seem to be contrasting rather than parallel. The phrases are also still asymmetric, but this time they are shortened by one measure each when compared with the initial introduction of the period in the very beginning of the piece. Again there is a cadential extension just like at the termination of the A theme before.
This is a cute little piece, and was enjoyable to delve into...
Bartok - Mikrokosmos "Peasant Dance"
The first four measures are a sort of vamping introduction with a g and an f sharp together on the first beat (the piece is in 2/4) and a g an octave down on the second beat. The f then becomes natural as the melody in the right hand begins, giving the listener a sudden jolt--for it really does seem almost tonal for a moment. The right hand makes one eight measure phrase and ends on a half cadence on G the dominant(we actually turn out to be in c minor, although the key signature marks no accidentals). After a pickup from the last bar of the first phrase and then six measures, we come to an almost deceptive feel which then resolves in the right hand to more a tonic -- running up the scale with c on the first beat. However, in the left hand, the tonality does not fit at all with c minor. By measure twenty five, we have a repeating G in the right hand voice, which could function as insinuating a dominant, or even a progressive modulation into G, but underneath in the left hand, we have an e, a g# and a c# that really wash out any c minor or G major that might have been inferred. These last nine bars of A plus pickup represent for me a transitional section (as that c# turns into a d flat) that perhaps elides with a sense of closure for the A section.
In B we are now in Ab major and the temp picks up a little. Also, he switches off the voice in a little contrapuntal immitation. The two voices (each hand only playing one line) begin to interact more closely until they unite together in a unison run all the way to the bar of 3/4 and the return of G in the bar following. I could almost divide this up into two phrase groups that any real cadence, but suggest an IAC after 8 measures, and then a HC after the next ten measures--thus making this section open.
Again we have four measures of introduction, though up an octave with the right hand playing out a syncopation on the g. The left hand plays much higher this time, and there are now sixteenth note runs in the right hand. In the thirteenth measure of this A' section, both hands join in complimentary 16th note runs, and suddenly change texture completely in bar 16. There the dynamic is marked forte, the tempo is up (as it was even slower than the first A originally), and we have this terminative section that establishes the feel of c minor firmly though in a rather unorthodox sense, ending on an open fifth on G. So A' is also open, ending on a half cadence.
The section divisions are marked with an added bar of 3/4 (both at the end of A and B) and through tempo markings. A seems to not only be open in the sense that the right hand sung out a G until the end of the bar, but that c# functioned as a d flat for the B section, giving it a HC feel in the Ab major as well. Also the differences in texture make each section distinct. As for A' ending in the original key, at least it does not play the c# so at least leaves us with a HC feel in the original key. In A', I cannot really seem to find cadences or phrase groups, though the score is divisible through texture changes and tempo markings. Because the sections are small and lack higher organization in themselves, I see this as a simple ternary in which all sections are open (though B and A' end on their own dominant, and A seems to want to mix both the dominants of B and A').
Schumann: Myrthen, Op. 25, "Dedication"
Part A, (mm. 1-13), a phrase group in Ab major, represents a tonally closed expository section ending on a PAC. There may be argument for a Half Cadence at the end of measure 5, but I don't really hear one. Schumann uses varied rhythms and articulations to correllate with the lyrics. The busy accompaniment moves under a soaring soprano line. It is a beautiful exposition, with the high point of the section coming on the seventh of a secondary dominant chord. The section ends ritarding and decrescendoing gracefully into a PAC.
The changes in tonality, accompaniment style, and motivic content provide the contrast necessary for part B. In the foreign key of E major, we encounter another phrase group. The first two phrases are nearly identical, ending on HC, with the second phrase embellishing the B theme. The final phrase is clearly developmental and transitional, ending 4 bars later, leaving this section tonally open. Important phenomena include dynamic changes, embellishments, modulation, and a rhythmically slow contrasting theme.
After the middle section, we transition back to the A section and Ab major, signalled by a ritardando. The recapitulation is varied, starting and ending different from the beginning. Again I think I would consider this to be a phrase group, however, there are a few more PACs making this concluding section a bit more organized. The piece ends on a PAC, followed by a cadential extension in the piano.
"Peasant Dance", by Bartok
The A section is in the key of g minor starting in measure 4, due to the amount of leading tones at the beginning, but it is kind of difficult to say because of the occurence of Ab's later on. Actually, the more I look at the score, it's very hard to tell what key this is in. I thought of the Ab major chords as Neopolitan chords. Anyway, The left hand begins the piece the first four measures with a very heavy feeling; the mood of the piece changes many times. I felt an IAC at the end of measure 12, but only very briefly. I felt section A was a period made up of 2- eight measure phrases. Measure 21 repeats the motive in measure 19, and Bartok plays around with it rhythmically through syncopation, giving it more of a compound as well as an accelerated (yay) feeling. I felt this section (measures 21-27) as being terminative as well as a transition to the B section.
Measure 28 begins the B section, this time with many added Db's, as well as some Gb's. There are 8 measures of kind of a call and response between the left and right hand, until in measure 35 they being to mesh together more. I felt like maybe this could be in f minor, because the f seemed the most tonic to me. Again, Bartok majorly plays around with syncopation, more in the B section than anywhere else. Measure 46 is terminativeand again, transitioning again back to the A section. It ends tonally open.
The return to the A section isn't exactly like the beginning A section, and is more of a variation of the A section. You can still hear the melodic line standing out from the 16th note runs, however. The A section ends tonally closed (because the piece itself wouldnt be closed) The tempo by this time has changed a little, but sounds much faster because of the 16th notes. I noticed that each section in this example of ternary form is independent from each other, and is additive.
The left hand also just plays the chords throughout the piece, with the melody being solely in the right hand.
Peasant Dance from Mikrokosmos - Bartok
Chopin - Prelude in F#, Op. 28 No. 13
It is in simple ternary form. The first A section, "Lento," is 20 measures long and is comprised of an extended double parallel period. The first half is made up of two asymetrical phrases (4 and 3 measures long, respectively), both ending with half cadences (I'll call them 'a' and 'b' from now on). In measure 8, Chopin uses a "snakey" line in the left hand to descend down the F# sacle from C# to the tonic, which begins the second half.
The second half of this period begins with the same 4 bar phrase from the first half, varied in that the rhythm of the melody is embellished. However, the second phrase is varied in an important way - it centers first arond the IV chord (Chopin uses a V7/IV instead of I). This phrase ends with a very unsatisfying half cadence, which leads into a third phrase - thus making the period extended.
The third and final phrase has this basic progression - V/ii ii V I. The phrase is extended from the third beat of m. 18 through measure 20. This extension has a terminative feel, so the first A section is strongly closed.
The B section begins with two phrases that have the progression ii V I first centering around the dominant (E), then the subdomimant (B). This sequence feels pretty stable and these four measures are therefore expository. However, the second phrase is extended with a transitional section that lasts from m. 25 to m. 28. It ends with a PAC in F# that has an F# pedal bass.
The return of A at the Tempo I sounds like the b phrase of the first A section, because it begins with the V7/IV chord. It begins with a contrasting period this time, with two asymmetrical phrases (3 and 2 measures each). Then Chopin added an extension that has a terminative feel from measures 34 to the end.
This piece has many of Chopin's trademarks - tempo rubato, which gives the piece an improvisatory feel, and a very sensitive, lyrical melodic line. It makes me feel like I'm in a cozy living room watching a fire calmly flickering in the hearth.
Man - boringly in-depth but I was especially interested after analyzing Chopin's Mazurka. The two are very similar formatic...ally...
Chopin: Prelude in F# Major Op. 28 No. 13
We start off with a repeated phrase group. The first five measures produce a I-I-I-V-I effect ending on a PAC. This phrase is repeated. The chord are played on the downbeat, with arpeggiations on the next 2 beats. The third time through we have a shift, instead of the V chord we delay it with a V/ii, followed by a modulation to the dominant, with a V chord held through two measures before resolving to our PAC in the dominant. Next we have a quick wandering passage that returns us to the original key, which is repeated, with small changes. When we repeat this section a Non-chord tone grabs our attention, signaling a larger change is about to occur. This NCT (a fa in a I chord) doesn't really change our key, but allows us to elaborate on the original theme, adding an extension to the section, moving away from the PAC deceptively (the fa's resolution would make it an IAC anyway), before resolving finally after a 4 measure extension to a PAC in F# Major, closing the section. We have another short linking measure, leading us down to our B section. The B section begins in D# minor (relative minor) and we have a significant timbre change at the eighth notes take on a different feel, instead pulsing (double-stopped) instead of just adding a coloring to the downbeat. The melody is a little slower, as the eighth notes become more filler material, the melody is allowed more breadth of phrasing. This section is much shorter than our A section, consisting of only one repeated phrase. Although we are in D# minor we really tonicize other keys, adding to the transitional feel of this section. We cycle through keys, with simple cadences in each, never feeling true stability until the F# Major returns, finally ending with a PAC. Our return of the A section is half as long as our original, as we move straight to the second time through. We have the return of our NCT as well as the extension that is tied to it. We PAC to end the piece, but still remain wandering a little, as the melody doesn't settle right away, extending it two bars further, before finally settling down.
I love this piece because I can totally see all the things it is a precursor (sp?) for. Chopin's sense of pitches and their interplay can directly be linked to later 19th century works, as well as jazz music of the 20th century. I could definately feel the wandering line of a jazz piece, as the chords were fairly simple, but the direction Chopin took them in was not exactly expected. I would consider this a simply ternary piece, but barely. We do have two complete sections, but the return of the A could easily be tied to the B section. I'm not convinced that this isn't a rounded binary form, since the end of B and return of A lack a definately delineation betwen the two. The A section is closed, since we begin and end in the same key. Since the B section moves to the relative minor we do fit the criteria of having separate keys, and the thematic shift is evident. However, I'm not toally convinced that Chopin wasn't thinking rounded binary...

Bartok Peasant Dance
the B section moves slightly faster than what was previously heard. the hands take turns playing eighth notes, so there is constantly an eighth note pulse. the hands take a scalar run together as the B section comes to an end. to me, the section does sound tonally open, but transitions somewhat smoothly into the return of the A section.
When the A section does return, it is not exactly the same as the first exposition melody. the melody in the right hand is much more active with 16th note runs. it does play on the first melody, however.
it is obvious to the listener that the A and B sections are independent from each other, both rhythmically and tonally.
Chopin - Prelude in F-Sharp Major Op. 28 No. 13
Once again we are in the simple ternary section of the book, and this is the form of this prelude.
The first phrase consists of the first six measures. This phrase modulates from F-sharp major to C-sharp major ending on a PAC though the PAC is short lived. You could make arguments for some PAC's in F-sharp throughout the first few measures, but the initial chord is immediately followed by the seventh in the bass which takes away the strength of the
The B section has major differences compared to the A section. The eighth notes in the left hand become double stops, an eighth note line is added to the right hand, a key change and markings of "piu lento" and "sostenuto" on the music. I don't have a 100% feeling of key for this section, but since most of the bass line is hanging around the key of D sharp minor, it is probably the key. Once again, there are feelings of tonic but not strong enough to be a cadence. This section is nine bars long and modulates back to the original key of F sharp major.
The return of the A section is only ten bars long. The first couple of bars are parallel with the opening A section, but then there is additional development of the main theme and a PAC in F sharp major in the sixth bar, eighth bar, and the last two bars serve a terminative function to end in the key of F sharp major.
