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…
Use your ears and knowledge of scales and chord structure to “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 helps to develop an enormous chord vocabulary, one that you will know intimately in many ways: by brain, by eye, by ear, by finger, by body, and by heart… and builds a solid foundation for fluent improvisation.
