DRILL: Practice Fig. 3 for automatic facility with the twelve major tenths (or their indicated inversions) and their swing chords. (The problem of weight displacement involves several factors: 1. Free, pendulum-like arm movement; 2. Loose wrist; 3. True facility which can only result from completely "blind" automa-tion (Remember, the hand moves faster than the eye.)

LESSON 8.

The Dominant Swing Chords The tonal combination for all dominant swing chords is 5 7 1 3
