Why it sounds like that

F 11th stacks a major 3rd, perfect 5th, minor 7th, major 2nd, and perfect 4th above F. The minor 7th gives it dominant pull, and the added 11th softens the F 9th sound.

What goes wrong with F 11th?

  • The 2nd string buzzes because the index barre lifts slightly at the 1st fret.
  • The pinky mutes the 1st string by flattening onto it instead of fretting it cleanly.

When to use it

F 11th works as a dominant in B♭ major progressions like B♭–E♭–F–B♭, the I–IV–V–I. It suits blues, funk, and jazz-rock where the 11th adds grit over F major.

Changing to and from F 11th

  • Sliding the shape up one fret to the 2nd fret gives F♯ 11th.
  • Sliding the shape up two frets to the 3rd fret gives G 11th.

Which voicing to use

The 1st fret position keeps F in the bass for a root-position sound. The F11/A inversion at the 3rd fret puts the third in the bass, making the chord brighter and less stable.

Common questions

How is F 11th written?

F 11th is written as F11 or simply F. The root is F.

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

F 11th adds the 11th note B♭ to the F 9th chord. The 11th creates a softer, more suspended sound than the sharper dominant quality of F 9th.

Why does F 11th contain a tritone?

F 11th contains a tritone between the major 3rd A and the minor 7th E♭. This interval creates tension that resolves to the tonic chord in B♭ major.
