The light version of Bmaj7

Bmaj7 B D# A#

Drop the fifth and keep B D# A#: root, third and seventh. Pianists use this shell voicing in the left hand, because those three notes already say "Bmaj7".

Learning Bmaj7 step by step

  1. Start in root position: B, D#, F#, A#, four times, eyes on the symbol.
  2. Walk up through the inversions (D# F# A# B, F# A# B D#, A# B D# F#) without lifting the whole hand.
  3. Play it in its ii-V-I, C#m7 → F#7 → Bmaj7, four beats per chord.
  4. Finally meet it in random order between other chords, with a check on every note.

Short daily rounds fix Bmaj7 in memory faster than one long practice a week.

Bmaj7 in keys and progressions

  • Bmaj7 is the Imaj7 of B major and the IVmaj7 of F# major.
  • It is where a ii-V-I in B major lands: C#m7 → F#7 → Bmaj7.
  • Inside Bmaj7 sits D#m (D# F# A#): play D#m over B in the bass and you get Bmaj7.

ii-V-I: C#m7 → F#7 → Bmaj7 · B
