The Carl Fischer Solo Series is designed to help all levels of instrumental soloists improve their performances by making practice time more productive with the included piano accompaniment. The audio contains a beautifully recorded piano accompaniment performed by John Walker, a professional pianist with years of experience accompanying soloists of all ability levels. The Solos Series is an invaluable tool and is presented in three graded levels: Beggining (Gr.2), Intermediate (Gr.3), and Advanced (Gr.4-5). As an added bonus, the faster pieces have a second track with the piano accompaniment at a rehearsal tempo to assist in the preparation of the piece.
