A three-note Bbmaj7
The fifth (F) adds little colour. Bb D A is enough to sound like Bbmaj7 and is far easier to reach.
Four 7th chords on Bb
Play the four in a row and listen to each colour.
Learning Bbmaj7 step by step
- Play Bb, D, F, A slowly in root position and say "Bbmaj7" each time.
- Climb the four positions: Bb D F A, then D F A Bb, F A Bb D and A Bb D F, and back down.
- Play it in its ii-V-I, Cm7 → F7 → Bbmaj7, four beats per chord.
- Finally meet it in random order between other chords, with a check on every note.
Short daily rounds fix Bbmaj7 in memory faster than one long practice a week.
