History
Two-Part Invention No. 9, BWV 780 belongs to Bach's two-part Inventions. The earlier teaching notebook for Wilhelm Friedemann was begun in Köthen on 22 January 1720. Bach made a separate fair copy of the collection in 1723, revising its presentation and order. These dates mark stages in the collection's history, not the exact day this individual piece was composed. The collection reached print in 1801, long after Bach's lifetime.

How to practise it
Let the descending upper line and rising lower approach retain separate shapes.
- Practise the descent into tied D-flat, listening to the end of the gesture.
- Practise the lower approach into its sixteenth continuation.
How hard is it
Sustained notes and moving sixteenth-note lines need different articulation and balance. The added ornament vocabulary makes this a more involved intermediate reading and voicing task.
