(De Haske Play-Along Book). Classical Violin Trios is an easy-to-play collection for three violins, or two violins and cello. The pieces in this book were all originally written specifically for violins. Many are well known, but some are less familiar. Included are works by Mozart, Bach, Haydn, Corelli, Mazas, and others. In some cases, the optional cello part has been adapted from the original to give the music a better overall sound. This fabulous collection provides ideal material in the 1st position which can be used alongside any learning method, and makes playing with a trio very enjoyable. All pieces in position 1.
