The Invention and Sinfonia No. 2 in C minor by J.S. Bach are essential works for developing independence between the hands. The Invention (BWV 773) focuses on two-part counterpoint and it’s practically a canon, while the Sinfonia (BWV 788) raises the stakes by introducing a third voice — which means three independent lines to manage with just two hands.
Practice Notes for Study and Performance
A few things worth keeping in mind while working through these pieces:
- Highlight the imitation: invention BWV 773 is practically a canon, so make sure you highlight the imitation by using articulations and dynamics in a consistent manner.
- Follow the subject: in both pieces but especially the sinfonia, make sure the main theme is heard clearly every time it enters in a new voice. If it gets buried, the whole point of the counterpoint is lost.
- Finger independence: The Sinfonia No. 2 is particularly tricky because the middle voice is often shared between the hands. Focus on keeping the motion smooth during those exchanges.
- Listen for the dialogue: Bach’s music is a conversation between voices. Try singing one part while playing the other — it forces you to actually hear the counterpoint rather than just play the notes.
As always with Bach: slow down, take the hands apart, and build it back up snippet by snippet. There’s no shortcut here — but once it comes together, it’s one of the most satisfying things you can play.
