Features pieces using 2nd finger, and backward and forward extensions. Offering a range of styles from folk to jazz , this work features duets with parts of equal difficulty. It includes a Music Fact-Finder page to help explain words and signs and also includes a CD with performances of all the pieces to play along to.The Cello Time books are more conventional and make excellent use of technology in the shape of CDs with very imaginative backing which includes the cello part. My pupils loved them . . . In both books the progression is excellent, the pieces not too long and there is a good glossary at the end . . . this is a most welcome publication.
