Chord-melody with all four voices within an octave, twelve keys
The classic block-chord style: take a melody
note and harmonise it with the chord's other notes stacked
directly below in close position — all four notes within
a single octave. The RH plays the whole block as a unit; the LH
typically plays a bass note an octave or two lower. Garner,
Shearing, and Wynton Kelly built the modern piano-trio sound on
this voicing.
For the ii-V-I here, the melody on top is the shell
tone of each chord (♭7 of ii, 3 of V, 7 of I). The ♭7
of ii drops a half step to the 3 of V; the 3 of V is the
same pitch as the 7 of I (it holds, no motion). One half-step
and one hold across the whole cadence — and the close-position
stacks underneath inherit that smoothness automatically.
