How to play High Notes & Low Notes

High Notes, Low Notes, and All The Notes In-Between, by John J. Haynie, Music Department, North Texas State University.

Inspired largely by Ernest S. Williams’ Secret of Technique Preservation, this book contains textual material and studies on embouchure development, tone and the breathing process, fingering and tonguing, together with a series of tonality studies on each tone of the chromatic scale.

Within each tone are studies on long tones, scales, trills, lip slurs, intervals, tonguing, chords. Widely used as study material in colleges, and considered an effective, systematic approach for preservation of technical abilities.
