Greetings,I am playing Invention 13 at maximum 70 bpm, but I think it is still slow.When I watch videos playing it, it is faster. However I saw in a book that there is a speed range for the Inventions of Bach.Which could be a fair speed for this piece?, in which speed range should the piece be played.
I would say play that invention at a slightly more than Andante speed, perhaps a light jog speed. Kind of like the speed you would embark on when at the baggage check to the gate when your flight is leaving in 10 minutes.
