Sonatina by Eugène Bozza is a piece for Four unequal Clarinets (an E flat Clarinet, two B flat and a Bb Bass Clarinet). Strongly lyrical, this piece, which lasts approximatively 7'50 minutes, is very interesting and quitechallenging to play. It explores the full high and low of the instruments, and requires some good ability of breathing and strong agility. It is divided into three main parts, which are: I. Allegro vivo, II. Calme (Quiet) andIII. Allegro Vivo. While the first and third sections are very cheerful and energetic, the second part is slower and more reflective. Eugène Bozza won different prizes at the Conservatoire de Paris such as the First Prizes forthe Violin, conducting and composition, as well as the Grand Prix de Rome. He composed several operas, chamber works and ballets among others.
