Schumann, Vogel Als Prophet, Op. 82
This piece is composed in simple ternary form. The piece begins in the key of B-flat major, and cadences in measure 4 with a PAC in B-flat major. From there we have a direct modulation to the key of F major and also cadence again after four measures, in measure 8 with a PAC in F major. We have two more phrases which are also four measures long. The third phrase is in the key of C major and ends on a IAC in measure 12, and the last phrase enters back into the original key of B-flat major which cadences on a PAC. The first two phrases are just that…a phrase group and the last two are more of a developmental section of the A section.
The A section continues on for a couple measures, but then changes rhythm, motive, dynamic, and it modulates to the key of G major. Once in the new key in cadences with a HC in measure 22 in G major. This section I view as a transitional section because it is just working the piece from the developmental section back to the A expository section, which goes through the same progression as the first one…fun fun fun….
