Nikolai Kapustin ： Piano Sonata No.9 Op.78

Kapustin’s Piano Sonata No. 9 combines the rhythmic vitality of jazz with the meticulous writing of the classical sonata tradition. Sharp syncopations, lively repeated figures, rich chords, and intricate passagework intersect as the music moves through contrasting characters. A particular attraction lies in the expressive melodies that emerge from the driving rhythms, as well as the vivid contrast between tension and release. In performance, it is important to maintain precise control of the complex rhythms while shaping flexible accents and phrases so that the music does not sound mechanical. Even in fast passages, keeping the notes even and clarifying the chordal sonorities and inner voices helps balance lightness with power.
