Description
In the Sonata for piano, Op. 5, written in 1924, Protopopov really developed his own vocabulary. The piece was written in one big uninterrupted movement of about 15 minutes long. All of the thematic material is derived from a three-note motif. By superimposing this motif on itself at different speeds, the composer has created a rich sound world that feels cohesive, yet never predictable.
