Why it sounds like that

F♯ 6th is built from the formula 1, 3, 5, 6. The major sixth D♯ added to the F♯ major triad gives the chord a bright, singing quality. Compare it with F♯ major, which lacks the sixth.

What goes wrong with F♯ 6th?

  • Letting the high e string ring: mute it with the ring finger, or the open E clashes with the chord.
  • Not pressing the barre hard enough on the D string, causing a buzz.
  • Flattening the pinky onto the B string and deadening it.

When to use it

F♯ 6th is the tonic in F♯ major, used in the I–IV–V–I progression F♯–B–C♯–F♯. Its bright colour suits rock and pop. Use it to add sparkle to an F♯ major chord in a chorus.

Changing to and from F♯ 6th

  • Sliding the shape up one fret to the 2nd fret gives G 6th; the barre and fingers move as a unit.

Which voicing to use

The 1st fret shape keeps the root F♯ in the bass and is the most common movable form. The F♯6/A♯ inversion at the 1st fret places the third A♯ in the bass, which gives a lighter, more open sound.

Common questions

How is F♯ 6th written?

The symbol F♯6 is the most common spelling, and the ASCII root is F#. It is also spelled G♭ in enharmonic notation for the same sounding root.

Can I play F♯ 6th with a barre at the 13th fret?

Yes, the 13th fret shape is a full barre with the root on the A string. It is easier to move up the neck than the 1st fret shape.

Why is the high e string muted in the 1st fret shape?

The high e is not a chord tone, so it must be muted to keep the voicing clean and avoid a clash.
