Dominant 7th ♯11 Chords on Piano

The 7♯11 chord is a dominant 7th with a raised eleventh (augmented fourth) — the signature chord of the Lydian Dominant sound. It creates a bright, sophisticated tension that is central to modern jazz harmony and tritone substitutions.

Each key below opens the full reference entry — keyboard diagram, audio, inversions, fingerings, and notation.

Formula: Root – Major 3rd – Augmented 4th – Perfect 5th – Minor 7th
Scale degrees: 1–3–♯4–5–♭7
Sound: Bright, sophisticated, Lydian Dominant
Symbol: 7♯11 (C7♯11)
Why ♯11 instead of natural 11? A natural 11th (perfect 4th) clashes badly with the major 3rd — they are only a semitone apart. The ♯11 avoids this clash entirely, sitting comfortably alongside the third. This is why jazz musicians strongly prefer 7♯11 over 7sus or dom11 for dominant chords. The matching scale is Lydian Dominant (4th mode of melodic minor).
