Stephen F. Goodyear: The New Recorder Tutor Book III: Descant Recorder:

The original and still popular recorder method can be used by people of no great musical ability who may be unable to take a music lesson by means of any other medium and can thus discover music together with their pupils. In fact the book takes no previous musical knowledge for granted. It contains a useful general introduction to music and the various elementary technical difficulties of learning to play the recorder are dealt with in the text. Ideal for providing a first thorough grounding in music and musicianship complete with a repertoire of exercises and many popular tunes that will make progress fun!
