On the staff

BDFA

On a treble staff, Bm7♭5 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, A, D, A and B, which are the degrees 1 ♭5 ♭7 ♭3 ♭7 1 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 six strings sounding four notes, the 1 and ♭7 appear more than once.

Four shapes for Bm7♭5 on 7-string guitar: Bm7♭5, Bm7♭5/D, Bm7♭5/F and Bm7♭5/A.

Every grip here is Bm7♭5, 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.

Where Bm7♭5 comes from

A chord does not belong to a single key. Each major or natural minor key listed here contains every note of Bm7♭5, which is why the same grip turns up in songs that otherwise have little in common.
