G♭6 — G♭, B♭, D♭, E♭ — is a G♭ major triad with an added major sixth. The chord lives in deep flat-side jazz; many ballads modulate to G♭ specifically because G♭6 has a unique mellow colour. It's enharmonic to F♯6 and to E♭ minor 7.

Common mistakes
G♭6 uses four flats (G♭, B♭, D♭, E♭). The most common confusion is with G♭maj7, which has F natural on top instead of E♭. The half-step lower top note in G♭6 gives a softer landing.
In context
G♭6 functions as a tonic chord in G♭ major. Wayne Shorter's "Footprints" passes through G♭-major colours; jazz ballads in G♭ use G♭6 at final cadences. The chord is also enharmonic to E♭ minor 7, which can serve as a pivot for modulation.
