'Clarinettissimo'' is an ideal supplement and a further tutor book to the standard work ''The Jolly Clarinet'', but can also used independently of it. The two volumes contain a balanced collection of classical and entertaining pieces, combined with technical exercises in all keys to provide an excellent foundation for learning play the clarinet properly. Playing is made even more fun with the addition of numerous duos and pieces for swinging to and playing around with, all featured on the accompanying audio download files.
