One of the most beautiful short pieces of music offering the listener inner rest and peace. Perhaps this music by Bach should have been composed for lute (or guitar), but the original belongs to the music written for Bach's son Friedemann, a lesser known collection, a notebook similar as for Anna Magdalena for piano / harpsichord - as beautiful.
Transcribed and performed by Georg Mertens. Also as video on youtube.
