6 ways to play Gm7♭5.
SoundRoot in gold, other voices in teal. Tap any note.
Close position
G · B♭ · D♭ · FRoot, third, fifth and seventh stacked within one octave — the reference voicing (piano; too tight to finger on guitar).
Drop 2
D♭ · G · B♭ · FTake the close voicing and drop its second-highest voice an octave. The most-used four-note voicing on guitar and in piano left hands.
Drop 3
B♭ · G · D♭ · FDrop the third-highest voice of the close voicing an octave: a wide, open sound.
Shell (1–7–3)
G · F · B♭Root, seventh and third only. The fifth is dropped — it adds nothing to the chord's identity — leaving a light, clear voicing.
Rootless A (3–5–7–9)
B♭ · D♭ · F · ABill Evans-style left-hand voicing: the third on the bottom, the ninth on top, the bass player supplies the root.
Rootless B (7–9–3–5)
F · A · B♭ · D♭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.

Understand the sound
Gm7♭5: from a pattern to a musical choice
What gives Gm7♭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 B♭, and degree ♭7 is F. Play G 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.
Separate the bass from the upper notes. If the low register sounds muddy, move the upper voices up an octave before adding more notes.
