Voicings · G♭△7 · Guitar
G♭△7 is spelled G♭ – B♭ – D♭ – F (1 3 5 7) — the tonic Imaj7 of a major key, and any maj7 chord. Here are 5 ways to voice it on guitar: drop 2, drop 3, shell, rootless a, rootless b. Every diagram is playable — press play to hear the chord, or “roll it” to hear the voices one by one, low to high.
The voicings
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 A-D-G-e, frets 4-4-3-1.
Drop the third-highest voice of the close voicing an octave: a wide, open sound. Strings A-D-B-e, frets 1-4-2-1.
Root, seventh and third only. The fifth is dropped — it adds nothing to the chord's identity — leaving a light, clear voicing. Strings E-D-G, frets 2-3-3.
Bill Evans-style left-hand voicing: the third on the bottom, the ninth on top, the bass player supplies the root. Strings E-A-B-e, frets 6-4-6-4 (position 2).
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-B-e, frets 13-11-11-9 (position 9).
Your next 10 minutes
Play G♭ – B♭ – D♭ – F individually, then choose a shell voicing above. Sing the highest note before playing the chord.
Compare the displayed voicings of G♭△7. Notice which note is highest in each. Repeat the two shapes with the smallest comfortable hand movement, leaving a beat of silence between them.
Play G♭△7 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 G♭, B♭, D♭, F. the tonic Imaj7 of a major key, and any maj7 chord. A fuller voicing is not automatically better: leave room for the melody and bass.
Understand the sound
Compare the major seventh with the root. Their half-step proximity is especially exposed when placed next to each other; change the register to soften it.
Here the third is B♭, and degree 7 is F. Play G♭ in the bass and compare these voices individually before combining them.
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.
Start with G♭ on string 6, fret 2. The next note B♭ is on string 6, fret 6. 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: G♭ · B♭ · D♭ · F. Then play a two-bar phrase from memory and leave two bars of silence.

The shell voicing (root, seventh, third) on strings E, D, G: three notes, one comfortable shape, and it still sounds unmistakably like G♭△7.
Start from the close voicing G♭ B♭ D♭ F and drop the second note from the top an octave: D♭ – G♭ – B♭ – F. It spreads the chord so it fits the hand — and on guitar it fits four adjacent strings.
