The voicings

5 ways to play Bm7♭5.

Sound
Root in gold, other voices in teal. Tap any note.

Drop 2

F · B · D · A
3frA7D3B1F5××

Take the close voicing and drop its second-highest voice an octave. The most-used four-note voicing on guitar and in piano left hands. Strings D-G-B-e, frets 3-4-3-5 (position 1).

Drop 3

D · B · F · A
4frA7F5B1×D3×

Drop the third-highest voice of the close voicing an octave: a wide, open sound. Strings A-G-B-e, frets 5-4-6-5 (position 2).

Shell (1–7–3)

B · A · D
2fr×D3A7×B1×

Root, seventh and third only. The fifth is dropped — it adds nothing to the chord's identity — leaving a light, clear voicing. Strings A-G-B, frets 2-2-3.

Rootless A (3–5–7–9)

D · F · A · C♯
2fr×C♯9A7F5D3×

Bill Evans-style left-hand voicing: the third on the bottom, the ninth on top, the bass player supplies the root. Strings A-D-G-B, frets 5-3-2-2 (position 1).

Rootless B (7–9–3–5)

A · C♯ · D · F
4fr×F5D3×C♯9A7

The companion rootless voicing with the seventh on the bottom. Alternate A and B so the top voice moves by step through a ii–V–I. Strings E-A-G-B, frets 5-4-7-6 (position 3).

Listen → play → apply
01

Build the sound

Play B – D – F – A individually, then choose a shell voicing above. Sing the highest note before playing the chord.

02

Change the top note

Compare the displayed voicings of Bm7♭5. Notice which note is highest in each. Repeat the two shapes with the smallest comfortable hand movement, leaving a beat of silence between them.

03

Comp with space

Play Bm7♭5 on beats 2 and 4 at 60 bpm for four bars, then on the “and” of beat 2 for four bars. Keep the same notes while changing the rhythm. Mute unused strings and test each fretted note for buzz.

Listen for this: The chord tones are B, D, F, A. the iiø chord of a minor ii–V–i. A fuller voicing is not automatically better: leave room for the melody and bass.

Understand the sound

Bm7♭5: from a pattern to a musical choice

What gives Bm7♭5 its identity?

Compare the flat fifth with a perfect fifth while keeping the other notes fixed. That one change turns a minor seventh into a half-diminished chord.

Here the third is D, and degree ♭7 is A. Play B in the bass and compare these voices individually before combining them.

Choose a useful voicing

Start with the smallest displayed shape you can play cleanly. Move its highest note into a comfortable register and listen for a clear melody above the chord.

Sound the strings separately before playing them together. If a note is muted, adjust the finger angle instead of squeezing harder.

Your guitar checkpoint

Start with B on string 6, fret 7. The next note D is on string 6, fret 10. Name both notes aloud before playing, then find the same two pitches in another octave.

Before moving on, close the diagram and name the notes: B · D · F · A. Then play a two-bar phrase from memory and leave two bars of silence.
