Practice Book for the Flute Book 6 Advanced Practice by Trevor Wye. Novello, SS, 37 pages. This is the final book for the flute in this series. Much of it is a continuation of the exercises set out in the earlier books; some of it breaks new ground. Most of it is for advanced players; some of it for the beginner and advanced player alike. Primary subjects covered are: tone, posture, technique, articulation, the top register, breathing and intonation.
