How to play F9 on piano
- Find F: it is the root and the lowest note of the chord in root position.
- Left hand: play F with the little finger (5), an octave below the right hand.
- Right hand: 1 on A, 3 on E♭, 5 on G.
- Leave out C: the chord is still recognisable without it, and the hand stays relaxed.
- Press the keys together, with curved fingers and a loose wrist, and let them ring.
