C-sharp major
The relationship of the minuet (in F-sharp major) and the trio (in F-sharp minor) continues the overall tension between major and minor. The minuet features a startling harmonic shift: its second half is suddenly interrupted by a fortissimo D-major chord, far remote from the home key, before a chromatic passage leads back to the dominant of C-sharp major. The trio is linked to the minuet by the rhythmic similarities of their opening motifs.
