Quinze études was adapted by Ulysse Delécluse (1907-1995) from the set of six works Sonatas and Partitas for Violin, initially written by J. S. Bach (1685-1750) in 1720. Started in 1703 and only finished in 1720, it alternatesbetween three sonatas in four movements and three partitas. In this baroque composition, each sonata has a four-movement structure consisting of a prelude, a fugue, and a more binary tempo for the third and fourth parts. Thepartitas, with a structure close to the gigue were slightly more varied due to the introduction of different elements. This transcription for the clarinet produced in 1953 by Ulysse Delécluse, a French clarinettist and professor,enables an easier access to this repertoire for clarinettists.
