How to play F#13
Take the four notes stacked as close together as they go, then drop the second voice from the top an octave. The gap it opens is what makes the chord sound like a chord rather than a cluster.
It lands on four adjacent strings, which is why it is the workhorse voicing on guitar.
F#13 has 11 of them, on the top four strings, the middle four strings and the bottom four strings, from the 2nd fret up to the 11th — every inversion the chord has: F# in the bass, A# in the bass, E in the bass and D# in the bass. The one to learn first is the E shape at the 2nd fret, which is the easiest grip here.
4 of them sit on the top four strings, so you can run the inversions up one set without changing strings — which is the whole reason to learn them as a family rather than as separate grips.
Start with 221300 — no barre and 2 open strings. 1 of the 9 shapes here sits in open position. 6 of the 9 need a barre. Together they cover the neck from the 1st fret to the 14th.

How to use F#13
F#13 is the V of B, and that is where it goes if it goes anywhere: the third and the flat seventh are a tritone apart, and both resolve by a semitone into B.
Voice by voice, F#13 → B. 2 voices move by a semitone, and 2 notes are common to both chords.
| In F#13 | Moves | In B |
|---|---|---|
| F#, the root | stays where it is | F#, the fifth |
| A#, the major third | rises a semitone | B, the root |
| C#, the fifth | falls a whole tone | B, the root |
| E, the flat seventh | falls a semitone | D#, the major third |
| G#, the ninth | falls a whole tone | F#, the fifth |
| D#, the thirteenth | stays where it is | D#, the major third |
In which keys. Every note of F#13 belongs to Ab minor (the ♭VII) and B major (the V, the dominant).
