All pieces are included on the accompanying audio, as a full version and as a piano accompaniment.
Volume 2 (easy to intermediate) contains pieces up to the 3rd position. As some new double bass tutors have a different approach in introducing position changes, volume 2 offers several pieces which reach the 2nd position, some pieces using only 1st and 3rd positions and some more difficult pieces which encompass all positions from half to third position. - the publisher
