BWV 907 is a charming, rarely performed keyboard work by J.S. Bach that balances a brief fantasy section with a lively, concise fugue. Its structure highlights Bach's mastery of the fugal style in a format more approachable than his larger keyboard works.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: independent voices that must each sing on their own line; ornaments that need to sound effortless, not squeezed in; and fine finger independence within the hand.
Beyond that, expect precise articulation — the difference between crisp and blurred is the piece, and continuous sixteenth-note figuration that must ripple, not chatter.
The primary challenge lies in maintaining consistent articulation and clarity in the fugue's subject throughout the contrapuntal lines.
