Ich bin in mir vergnügt (I am content in myself), BWV 204,[a] is a secular cantata composed by Johann Sebastian Bach in Leipzig between 1726 and 1727.
[1] Hunold and Bach are assumed to have met,[2] but the librettist died in 1721, which is well before the cantata appears to have been composed.
[1] The cantata is scored for soprano soloist, flauto traverso, two oboes, two violins, viola, and basso continuo.
The first aria is characterized by a "restless feeling of effort" beginning immediately after the short instrumental ritornello, and is the only one in da capo form.
The final movement is the only one to include all instrumental parts, with a dance-like opening theme and an ABAB structure.
