Composed in 1956 by Bohuslav Martinu, the Sonatina for Bb Clarinet and Piano is a neo-classical piece. 

This work, to be played as a single movement has been written in three different sections: Moderato, Andante and Poco Allegro. The rhythms are reminiscent of a Polka and a March and the piece contains unexpected syncopation. 

Being one of Bohuslav Martinu‘s later works, it was written in New York, after he spent some time in Paris.

Bohuslav Martinu (1890-1959) was a Czech composer and a violinist. Even though he was interested in different style, including Romanticism, Jazz and Expressionism, he wrote mainly neo-classical pieces, including 16 symphonies, 14 ballets and 15 operas.
