HOW TO PRACTISE IT
Six steps to a clean loop.
- Play each chord on its own: Gm7, C7♯9, Fmaj7 and C7b9. Press play on the chord card, then match the sound.
- Use light pressure; the ukulele's nylon strings need far less force than steel.
- 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.
- Strum down on every beat, then add an up-strum between beats with a loose wrist.
- 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.
F major has 1 flat; its relative minor key is D minor.
