McCoy Tyner modal vamp — the Coltrane-quartet piano sound on one dorian chord (G minor here). The left hand strikes a low open fifth plus octave (G–D–G) on the downbeat and lets it ring like a drone; the bass pedals root and fifth under it. The right hand never plays a triad: it jabs quartal voicings — stacks of perfect fourths, D–G–C–F and E–A–D–G — on swung off-beats, sliding between the two shapes.
The off-beats are swung at triplet positions (and-of-1 = 0.667). Drums: swing ride, hi-hat on 2 and 4, the kick feathered softly on every quarter, a couple of snare triplet jabs in the Elvin Jones manner.
Listen for the openness: with no thirds stacked in the right hand the harmony floats, so the rhythm of the jabs carries the music. Practice: hold the left-hand fifth with the pedal and move the two fourth shapes up and down the dorian scale in parallel — that sideways planing is the Tyner vocabulary.
