It sounded pretty bad. the first few were nice but when accidentals were added. it sounded awful. I mean, it is at many times just... musically wrong! the notes sometimes make no sense when played. however, it does work your left hand a lot. I don't think there's many different bow strokes. well, apart for legato and detache. I just played through all the music today to practice sightreading, and it wasn't too bad for that purpose. (except for the seemingly random accidentals)
