Why it sounds like that

F♯ 5th is built from the formula 1, 5, using the root F♯ and its perfect fifth C♯. The perfect fifth gives the chord its strong, hollow sound. Compare F♯ 5th with F♯ major, which adds the major third A♯.

What goes wrong with F♯ 5th?

  • Letting the G or C string ring open because the muting finger is not touching it.
  • Pressing the E string too hard and pulling it sharp.
  • Flattening the middle finger onto the C string and accidentally fretting it.

When to use it

F♯ 5th functions as a power chord in F♯ major progressions like F♯–B–C♯, the I–IV–V in F♯ major. F♯ 5th suits rock and metal where a neutral fifth sound is preferred.

Changing to and from F♯ 5th

  • Move from F♯ 5th to B major by lifting the middle finger and placing it on the C string 3rd fret while the index stays on the E string 2nd fret.
  • Slide F♯ 5th up one fret to G 5th by moving both fingers together from the 2nd fret to the 3rd fret.

Which voicing to use

The 2nd fret position keeps F♯ in the bass for a grounded sound. The F♯5/C♯ inversions put C♯ in the bass, which lightens the chord and works well when moving to B major or D♯ minor.

Common questions

How is F♯ 5th written?

F♯ 5th is written as F♯5 or F♯. On a keyboard you may see F#5 because the sharp symbol is not always available. It is also spelled G♭ in enharmonic notation for the same sounding root.

Why does F♯ 5th sound different from F♯ major?

F♯ 5th omits the major third A♯, leaving only the root and fifth. Without the third the chord has no major or minor quality, which lets it fit both F♯ major and F♯ minor contexts.

Can I play F♯ 5th higher up the neck?

F♯ 5th has no higher position on this page, but you can play the F♯5/C♯ inversion at the 6th fret. That inversion puts the fifth in the bass for a lighter sound.
