The "12 Canons for 2 Violins" were composed to be teaching pieces, both for violin technique and for modern music technique, that could be used with a teacher so that the student could observe and then play back what the teacher was playing. They are musical enough to be used for recitals as well. #2 offers some challenges with chromatic fingering and is basically a unison line that diverges to create syncopations that would otherwise be difficult to play. They can all be played in first position. Please note the mp3s associated with each file sound much better than listening with general midi, and they are small files.
