Galt guitar chord

About Galt — shell voicings

It sounds maximum tension, barely holding together. Not one chord but an instruction: take the root, third and flat seventh, add any two alterations, and let the rest go.

How to play Galt
Root, third and seventh. The third and seventh, the guide tones, are what make the chord major, minor or dominant, so the fifth can go: it says nothing the symbol needs.
Three notes means a spare string, which is the real point. Put a tension on it.
Galt has 6 of them, on the bottom four strings, the top four strings, the middle four strings, strings 6-4-3-2 and strings 5-3-2-1, from open position up to the 13th — all in one inversion, so the bass note never moves. The one to learn first is the G shape at the nut, which is the easiest grip here.
Start with xx5607 — 1 open string and only 3 fretted notes. 1 of the 9 shapes here sits in open position. None of them needs a barre. Together they cover the neck from the 2nd fret to the 12th.
| Frets | Where | Bass | Top | Hand |
|---|---|---|---|---|
| 32x023 | open position | G, root position | G | 1 open string |
| 32x423 | 2nd fret | G, root position | G | all fretted |
| xx5423 | 2nd fret | G, root position | G | all fretted |
| 3454x3 | 3rd fret | G, root position | G | all fretted |
| xx5607 | 5th fret | G, root position | B | 1 open string |
| xx5687 | 5th fret | G, root position | B | all fretted |
| x-10-9-0-0-9 | 9th fret | G, root position | Db | 2 open strings |
| x-10-9-12-12-9 | 9th fret | G, root position | Db | all fretted |
| x-10-11-12-12-x | 10th fret | G, root position | B | all fretted |

How to use Galt
Galt is a dominant with its tension raised, so it still points at C — harder than a plain seventh does, because the altered tones sit a semitone from where they are going.
Voice by voice, Galt → C. 4 voices move by a semitone, and one note is common to both chords.
| In Galt | Moves | In C |
|---|---|---|
| G, the root | stays where it is | G, the fifth |
| B, the major third | rises a semitone | C, the root |
| D#, the sharp fifth | rises a semitone | E, the major third |
| F, the flat seventh | falls a semitone | E, the major third |
| Ab, the flat ninth | falls a semitone | G, the fifth |
