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 alternates between 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. The partitas with a structure close to the gigue were slightly more varied due to the introduction of different elements. This transcription for the clarinet produced in1953 by Ulysse Delécluse a French clarinettist and professor enables an easier access to this repertoire for clarinettists.
