Frédéric Chopin - Piano Sonata No. 3 in B Minor, Op. 58, 1st Movement (Synthesia)

The work opens on a martial note, the heavy chords and filigree in the opening of the first movement giving way to a more melodic second theme, eventually leading to the conclusion of the exposition in the relative major, D. This exposition is quite long compared to other sonatas and it may be for this reason many pianists choose to omit the exposition repeat. Motives of the original theme emerge in the development, which, unconventionally, returns to the second theme (as opposed to the first) for the recapitulation, which is in B major.
