Why it sounds like that

F♯ 11th combines a major triad with a ♭7, 9, and 11: 1–3–5–♭7–9–11. The 11th (B) adds a suspended colour over the dominant seventh. Contrast with F♯ 9th, which omits the 11th.

What goes wrong with F♯ 11th?

  • The B string is muted because the index barre is not pressing hard enough at the 2nd string.
  • The high e string is deadened by the pinky accidentally touching it before fret 4.
  • The ring finger leans on the B string, preventing it from ringing.

When to use it

F♯ 11th is the V chord in B major, resolving to B major in progressions like B–E–F♯–B (I–IV–V–I). Its dominant tension suits rock, blues, and funk, especially when you want a fuller sound than F♯ 9th.

Changing to and from F♯ 11th

  • Move to B major by lifting the ring and pinky fingers, then barre the 2nd fret and place your ring finger on the 5th string at fret 4.
  • Slide the shape up one fret to the 3rd fret for G 11th.

Which voicing to use

The 2nd fret root-position voicing keeps F♯ in the bass for a grounded sound. The A♯ inversions put the third in the bass, making the chord brighter and less stable, useful when a bass player covers the root.

Common questions

How is F♯ 11th written?

F♯ 11th is written as F♯11 or F#11. The root is F♯, also written F#. It is also spelled G♭ in enharmonic notation for the same sounding root.

Why does F♯ 11th sound so dense?

F♯ 11th contains six different notes, including the 9th and 11th. That density creates a rich, cluster-like quality that works best in a band mix where other instruments fill the lower register.

What is the difference between F♯ 11th and F♯ 9th?

F♯ 9th contains F♯, A♯, C♯, E, and G♯. F♯ 11th adds the B, the 11th, which creates a suspended feel against the third A♯. The added note makes F♯ 11th more colourful but less direct.

Can I omit the 5th in F♯ 11th?

Yes, omitting the C♯ reduces clutter without changing the chord's function. The essential notes are the root, third, ♭7, and 11th. The 9th can also be dropped if needed.
