F♯6 is spelled F♯ – A♯ – C♯ – D♯ (1 3 5 6) — a tonic alternative to maj7, especially on the last chord of a tune. 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, frets 4-4-3.
Drop the third-highest voice of the close voicing an octave: a wide, open sound. Strings A-D-B, frets 1-4-2.
Root, seventh and third only. The fifth is dropped — it adds nothing to the chord's identity — leaving a light, clear voicing. Strings E-A, frets 2-1.
Bill Evans-style left-hand voicing: the third on the bottom, the ninth on top, the bass player supplies the root. Strings G-B-e, frets 3-2-4.
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-G-B, frets 4-3-2.

Play F♯ – A♯ – C♯ – D♯ individually, then choose a shell voicing above. Sing the highest note before playing the chord.
Compare the displayed voicings of F♯6. 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 F♯6 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 F♯, A♯, C♯, D♯. a tonic alternative to maj7, especially on the last chord of a tune. A fuller voicing is not automatically better: leave room for the melody and bass.
Understand the sound
The sixth replaces the major seventh. Compare the softer root-and-sixth relationship with the half-step tension of a major seventh.
Here the third is A♯, and degree 6 is D♯. Play F♯ 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 F♯ on string 6, fret 2. The next note A♯ 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: F♯ · A♯ · C♯ · D♯. Then play a two-bar phrase from memory and leave two bars of silence.

The shell voicing (root, seventh, third) on strings E, A: three notes, one comfortable shape, and it still sounds unmistakably like F♯6.
Start from the close voicing F♯ A♯ C♯ D♯ and drop the second note from the top an octave: C♯ – F♯ – A♯. It spreads the chord so it fits the hand — and on guitar it fits four adjacent strings.
