I’ve added chords to a few violin exercises. I’ll keep adding more as I find the time and energy.
Besides violin, I also play acoustic guitar. It is impressive how quickly my speed improves using Strum Machine, especially when playing the Etude No 2 listed here. That Etude feels like it was written for the acoustic guitar! Though still a little ragged, I can play it at 75 bpm. It will get easier the more I work on it.
By the way, follow the link and the spelling of Wohlfahrt is correct. It was wrong once but the fixed version didn’t make it through the link.
