Triad shapes, in and of themselves, are intrinsically strong harmonic structures. A commonly-used voicing for a Minor Seventh Chord is to play the root in your left hand and the triad formed by the b3, 5, and b7 in your right.
One might conceive of this Cm7 voicing as Eb/C…
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.
