A three-note Abmaj7
Root, third, seventh: Ab C G. It is the shape to learn first, and it moves smoothly to the next chord.
Learning Abmaj7 step by step
- Play Ab, C, Eb, G slowly in root position and say "Abmaj7" each time.
- Climb the four positions: Ab C Eb G, then C Eb G Ab, Eb G Ab C and G Ab C Eb, and back down.
- Play it in its ii-V-I, Bbm7 → Eb7 → Abmaj7, four beats per chord.
- Finally meet it in random order between other chords, with a check on every note.
Short daily rounds fix Abmaj7 in memory faster than one long practice a week.
