A logical and musical next step is play the most basic voicing for a C Major Seventh chord in our left hand in block form…
Doing so frees your right hand to play a melody or improvise.
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.
