BmMaj7

  1. B1
  2. D♭3
  3. F♯5
  4. A♯7

BmMaj7 is B, D, F♯ and A♯.

BmMaj7 has four notes, and the 6-string bass has six strings to play them on. The rest of this page shows how a hand fits one to the other.

On the staff

BDF♯A♯

On a bass staff, BmMaj7 is written B, D, F♯ and A♯.

The staff shows the notes one after the other, then together. Written this way the chord is in close position, which means each note sits as near to the one below it as the spelling allows. A guitar almost never plays a chord in close position.

Strummed from the lowest string to the highest, this grip sounds B, F♯, B, D and A♯, which are the degrees 1 5 1 ♭3 7 rather than the 1 ♭3 5 7 of the written chord. The root is the lowest note, so this grip is in root position and sounds the way the written chord suggests. With B in the bass and five strings sounding four notes, the 1 appears more than once.

Strummed from the lowest string to the highest, this grip sounds D, A♯, D, F♯ and B, which are the degrees ♭3 7 ♭3 5 1 rather than the 1 ♭3 5 7 of the written chord. The lowest note is the ♭3 rather than the root, so this grip is in first inversion, written BmMaj7/D. It has the same notes as the root-position grip, but with D in the bass it sounds different. With D in the bass and five strings sounding four notes, the ♭3 appears more than once.

The lowest note is the 7 rather than the root, so this grip is in third inversion, written BmMaj7/A♯. It has the same notes as the root-position grip, but with A♯ in the bass it sounds different.

Four shapes for BmMaj7 on 6-string bass: BmMaj7, BmMaj7/D, BmMaj7/F♯ and BmMaj7/A♯.

Every grip here is BmMaj7, but no two of them sound alike. A chord with the root as its lowest note is in root position, and a chord with any other note at the bottom is an inversion. On a keyboard you choose the inversion you want, but on a neck the shape your hand can reach usually decides it for you. When a grip sounds a note more than once, the fretting hand decides which note that is, not the harmony.

Every grip above is a handful of the notes on this diagram, and none of them uses a note that is not shown here.
