History
Invention No. 13 in A minor, BWV 784 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.

What to listen for
Voices exchange
Hear the earlier presentation expand through exchanged lines.
How to practise it
Separate the upper broken figure from the lower held note and later answer.
- Practise the two sixteenth groups into the four eighths without changing pace.
- Practise the lower held-note approach before adding its moving answer.
How hard is it
Broken-chord figures move through changing registers while the other line continues independently. This is a useful intermediate coordination target, provided the player can keep the pattern musical rather than accent every position change.
