For a full, but simple and open sound, voice the Dominant Seventh Chord as a perfect 5th in the left hand and a Tritone of the two definitive tones (3, b7) in the right…
suitable for very sparse and light comping…
Using your ears and knowledge of scales and chord structure, “transpose” this voicing to all spellings in three musically-useful patterns:
- Chromatically Ascending: C > Db > D > Eb > E > F > Gb > G > Ab > A > Bb > B > C.
- Chromatically Descending: C > B > Bb > A > Ab > G > Gb > F > E > Eb > D > Db > C.
- Cycle of Dominants: C > F > Bb > Eb > Ab > Db > Gb > B > E > A > D > G > C.
Doing so will develop an enormous chord vocabulary that you will know by eye, ear, arm, hand, finger, brain, and heart… laying a rock solid foundation for fluent improvisation.
