Sonata in D major, K. 284, mozart

the theme is in rounded binary form. The A section is a parallel, symmetric modulating period (it goes from D to A major), ending on a PAC in measure 8. The pickup to measure 9 marks the short B section, and is not its own exposition. It's transitory because it's goes through a couple of keys before returning to the original key of D. The A section comes back, and prepares us for the final PAC in D.

var. 1-
It plays around with rhythm in this, and we feel as though we're in compound meter because of the tied triplets. Also affecting the rhythm is the change from constant downbeats at every other quarter rest in the first phrase to the quarter rests being on the offbeats. It kind of gives is a slowing down feeling. The modulations are still the same, as well as the cadences.

2-very drastic dynamic changes. (soft on each first phrase of the period, forte on the second phrase) More of a playful feel.

3-constant running 16th notes in only one voice. The left hand provides most of the harmonic structure.

4-Very noble feeling- more syncopated. The left hand now has the running 16th notes. Loud

5- dynamics change to piano. relaxing. slower than the var.'s before

6- very exciting. The bass line gives the three note introduction to the right hand's 16th notes.

7- change to d minor. very bittersweet. more trills. very slow

8-Back to fast, loud original key. Kind of a question and answer section between the right and left hand.

9. syncopated, varying dynamic degrees.

10. sounds like it's anticipating something (b/c of the right hand) Very transitional feeling. alot of accidentals

11. Mood changes-it seems to have settled in D major again. Very chromatic at times. this is my favorite variation. what do toricella and autograph mean?

12- very playful feeling again. Time changes to 3/4. I got this image of someone galloping away on a horse into the kind of sounds like that! and it ends on a pac in the original key...

NO that's wrong it's in sonata form expositon, development and recapitulation

the form is sonata form with exp., dev., and recap. Rounded binary form is [a] [b - a'] (with repeats for each bracket). The a' doesn't appear and there are not any repeats.

The whole piece is in sonata form, but as the author states, the theme is in rounded binary form. The theme is in mm. 1-17.

This post is about the last movement only. Everything stated is true. The overall form of the last movement is Theme and Variations. The form of the theme is rounded binary and every following form is rounded binary. There are 12 variations, and as you can see, there are posts about all 12 and how they are different from one another.
