Breakfast - Intonation Practice For Trombonists - An audio CD provides accompaniments for scale, chord, interval and ensemble drills suitable for daily practice. On the CD, only the tonic uses the equal tempered pitch: Other notes are adjusted to <> or << Just Intonation>>. Drone Tracks use the equal tempered pitch for each note, with A at 440 Hz.

This booklet, Breakfast, and its companion audio compact disc, provide accompanied scale, arpeggio, and interval practice in pure harmony - or just intonation - rather than equal temperament. Repetitive drills, suitable for use among warm-up exercises, teach the slide hand to go to the precise position required for each note, depending on its context in major and minor keys.

Tone is best, and endurance improves, when we are not lipping notes into tune.
