I was given this as a gift by a violin playing friend, having asked for it ! This is a 'Must Read and Do the Exercises' book for any flautist/flutist wishing to control their tone production properly. Mr. Seed is a brilliant player himself, and here he proves that he has the gift of giving the student ( and anyone else) an extremely clear explanation of how tone production, harmonics, articulation and intonation relate to musical phrasing and interpretation as I have seen and heard from the great William Bennett myself many times. As well as specific exercises there are also fingering charts for special fingerings in the top register and for harmonics in the second register (sensitive fingerings) with some musical examples from the repertoire showing their application. Highly recommended !
