Stride Tenths in G Major
The notes
| Chord | Notes (low → high) | Formula |
|---|---|---|
| Am9 | A – C – E – G – B | root · ♭3 · 5 · ♭7 · 9 |
| D9 | D – F♯ – A – C – E | root · 3 · 5 · ♭7 · 9 |
| Gmaj9 | G – B – D – F♯ – A | root · 3 · 5 · 7 · 9 |
Why it works
From Am9 to D9, 5 voices move (A1→D2, C3→F♯3, E3→A3, G3→C4, B3→E4) against 0 held tones. Into Gmaj9, 5 voices settle by step or small leap (total motion of just 34 semitones). Smoothness here is measurable, not a metaphor.
In G major, 2 of the 15 notes fall on black keys — a mixed terrain that is exactly why this progression must be practiced in every key, not just C. The lowest note is G1 in octave 1; below roughly C3, close intervals start to blur, and this voicing stays clear of that line.
Practice tip: play the progression rubato first and listen for the held tones, then put the metronome on 2 and 4 at a slow tempo. When the grab is automatic, move around the circle of fourths — you are coming from D and headed to C. Say the chord symbols out loud as you play; naming and hearing are different skills, and you want both.
Where G major lives in the repertoire
G major earns its keep through "Autumn Leaves" — the most-taught standard in jazz education spends half of every chorus cycling Am7–D7–G, this exact cadence, before dipping into its relative minor.
