Keys and moves for Bbsus2
- Bbsus2 works in the keys where Bb already lives: Bb major, F major and Eb major.
- It often comes back to Bb or slides to Bbm, because without a third it can lean either way.
A short Bbsus2 routine
- Find Bb, then add the other notes one at a time: Bb, C and F.
- Switch between Bb and Bbsus2 ten times without looking at your hand.
- Try Bbsus2 in 1st inversion, the position that sits closest to your last chord.
- Then test it in random order among other chords: recall under time pressure is what sticks.
Come back to Bbsus2 tomorrow: short daily sessions beat one long one.
