20th Century (1956). This popular sonata in 3 movements was revised in 1986 to shorten the lyrical section at the end of the first movement. Chromaticism and shifting keys in quick moving passages demand finger dexterity. Shifting meters, disjunct lyrical passages, double and triple tonguing are featured throughout. The transparent middle movement requires both a straight and harmon mute and allows the performer to showcase expressive qualities in a rubato style. Last movement is primarily at a brisk tempo, frequently explores the upper register up to high C, and utilizes changing meters to give a lively, unpredictable feel to this exciting movement.
