Key signature

Bb is the home chord of Bb major: 2 flats.

Its dominant

F7 (F A C Eb) is the dominant 7th that resolves to Bb.

Enharmonic spelling

Sheet music sometimes calls the root A# instead of Bb: same key on the piano, same major chord.

Where Bb shows up

Three major keys contain Bb:

  • I in Bb major
  • IV in F major
  • V in Eb major

Relative minor: Gm · Parallel minor: Bbm

A common progression from Bb (I - V - vi - IV): Bb → F → Gm → Eb. Move between inversions so the hand barely moves.
