About Faug7 — shell voicings
Faug7 is F, A, C# and Eb — F7 with the fifth raised a semitone.
It sounds strained and chromatic. The raised fifth is heard as a ♭13 sitting a semitone above where it is going, so the chord pushes harder than a plain dominant.

Altered dominant — the pull of a 7, sharpened.
Also written F7#5, F+7 or F7(#5). The same chord either way; which spelling you meet depends on who wrote the chart.
How to play Faug7
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.
Faug7 has 4 of them, on strings 6-4-3-2, strings 5-3-2-1 and the bottom four strings, from open position up to the 13th — all in one inversion, so the bass note never moves. The one to learn first is the F shape at the nut.
Start with 10122x — 1 open string and down at the nut. 1 of the 6 shapes here sits in open position. None of them needs a barre. Together they cover the neck from the 1st fret to the 14th.
| Frets | Where | Bass | Top | Hand |
|---|---|---|---|---|
| 10122x | open position | F, root position | C# | 1 open string |
| xx3645 | 3rd fret | F, root position | A | all fretted |
| x878x9 | 7th fret | F, root position | C# | all fretted |
| x-8-11-8-10-9 | 8th fret | F, root position | C# | all fretted |
| 13-12-13-x-14-x | 12th fret | F, root position | C# | all fretted |
| 13-x-13-14-14-x | 13th fret | F, root position | C# | all fretted |
