On the staff

BD♯F♯AC♯G♯

On a bass staff, B13 is written B, D♯, F♯, A, C♯ and G♯.

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♯, A, D♯, G♯ and C♯, which are the degrees 1 5 ♭7 3 13 9 rather than the 1 3 5 ♭7 2 6 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.

Six shapes for B13 on 6-string bass: B13, B13/D♯, B13/F♯, B13/A, B13/C♯ and B13/G♯.

Every grip here is B13, 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.

B, D♯, F♯, A, C♯ and G♯ on the whole neck
