(Meredith Music Resource). The most complete intonation resource for band directors! This book contains everything a music educator requires to approach fine-tuning intonation with their learn the origin of our pitch tuning standard * understand when to apply equal tempered vs. just tempered tuning * calculate the proper harmonic ratios for fine-tuning chords * identify the best tuning notes for each instrument * 14 steps for tuning chords * properly tune brass slides * improve your knowledge with over 70 tuning truths and myths. In addition to the above content, this resource includes intonation charts for tracking personal progress, along with extensively researched color-coded fingering charts for every instrument providing pitch tendencies and suggestions for alternate fingerings.
This book doesn't always clearly explain its concepts - I had to reread the section on Interval ratios so many times... But it does have some exercises and concepts that can be quickly used to help intonation. The fingerling charts are great as well!
Original review:
An excellent reference text that discusses methods of tuning for large groups and individual instruments. Includes amazing fingering charts and excellent tables that could help improve the wind band intonation if implemented!
