HOW TO PRACTISE IT
Six steps to a clean loop.
- Play each chord on its own: B♭m7, E♭7♯9, A♭maj7 and E♭7b9. Press play on the chord card, then match the sound.
- Keep the right hand curved over the keys and move it as one unit between chords.
- Set the tempo to 69 BPM and play the progression with one chord per bar. Compare the ♯9 and ♭9 versions back to back over the same ii and I.
- Play the left-hand bass note on beat one and the right-hand chord on every beat.
- Raise the tempo to 92 BPM once you can play the loop three times without stopping.
- Record one take, listen back and check for the sharper bite of ♯9 and the darker pull of ♭9.
Listen for
Aim for the sharper bite of ♯9 and the darker pull of ♭9. A common mistake is resolving too early, before the tension registers.
Why it works
Altered ninths are a half step away from chord tones of I, so they resolve by the smallest possible step.
A♭ major has 4 flats; its relative minor key is F minor.
