Johann Sebastian Bach - Sonata in A Minor for Solo Flute. Johann Sebastian Bach’s Partita in A Minor, BWV 1013, is believed to have been composed around 1720–1723, during his years at the court of Prince Leopold in Köthen, although its precise date and circumstances remain uncertain. Originally titled Solo pour la flûte traversière, the work survives in a single eighteenth-century manuscript and is Bach’s only known composition for unaccompanied flute. Its four movements: Allemande, Corrente, Sarabande, and Bourrée Anglaise, draw upon the traditional European dance suite, while its intricate melodic writing creates the impression of multiple contrapuntal voices on a single instrument.
