Prelude

Prelude (Allegro, completed October 12, 1950) is based on flowing arpeggios in sixteenth notes, possessing characteristics of an etude. By starting anacrusically with sixteenth rests placed on strong beats, a dynamic sense of syncopation is created throughout. Furthermore, the contrast with the tenuto melody line in the latter half of the piece, though brief, leaves a lasting impression.

Fugue

Fugue (3 voices, Allegretto, completed October 13, 1950) is a piece based on a sketch from July 25, 1934. It embodies a playful atmosphere, creating a vivid contrast with the flowing mood of the Prelude. Each note is emphasized with staccato, possessing a clear rhythmic feel, and the theme, spanning a wide range of intervals, scurries about. The dynamic range is also wide, from pianissimo to fortissimo, and accents on weak beats, colorful harmonies employing polytonality, and syncopation collectively create a vivid impression.
