Related chords

G♭m6 contains exactly the same notes as E♭m7♭5. Which name fits depends on which note is in the bass and what key you’re in.

Move a single note and G♭m6 becomes a different chord: drop the E♭ for G♭m, raise E♭ to F♭ for G♭m7, raise B𝄫 to B♭ for G♭6 and lower D♭ to D𝄫 for G♭dim7.

Where you’ll hear it

Notice the B𝄫 in G♭m6 (G♭ B𝄫 D♭ E♭): each note of the chord takes its own letter (G–B–D–E), so the minor 3rd has to be written B𝄫 rather than A — the same key on a piano, spelled to fit the chord.
