The six Cello Suites, BWV 1007–1012, are suites for unaccompanied cello by Johann Sebastian Bach. They are some of the most frequently performed solo compositions ever written for cello. Bach most likely composed them during the period 1717–1723, when he served as Kapellmeister in Köthen. The title given on the cover of the Anna Magdalena Bach manuscript was Suites à Violoncello Solo senza Basso (Suites for cello solo without bass).
