Volume 1 of the 30 Studies after JS Bach first proposes a transcription of the Partita for flute alone, BWV 1013. The first known source being an anonymous copy with no articulations or nuances, these are therefore proposed as an indication. For those who want to play this Partita in the original tone, it will play on the clarinet in C. The following studies are free adaptations of keyboard parts (French Suites, Well Tempered Keyboard) and Lute Parts. They have a pedagogical vocation and are conceived - to use the words of JS Bach himself in subtitle of his well-tempered Clavier, for the practice and profit of the young musicians eager to educate themselves and for the enjoyment of those who are already broken with this art.
