This 20th century solo offers a nice challenge for the advanced clarinetist. The first movement shifts between 6/8 and 9/8 times in a quick tempo. The second movement is short, in Andante and has an expressive melody with some ornamentations. The third movement is Vivace and has some time signature changes making the melody sharp and rhythmic. Overall, there are slurred and staccato passages in the technical spots, and many accidentals written in throughout. Range is near 3 octaves, low F(3) to High G(6). In the keys of Cm and Gm.
