Chord formula

Interval formula: 1 3 #5 b7. A dominant 7th with a sharp 5th (7#5). A tense, whole-tone dominant with a strong upward pull.

Chord tones

The 3rd–b7 tritone keeps the dominant pull, and the sharp 5th adds whole-tone tension and pulls upward. Don't play a perfect 5th alongside it.

Sound character

Tense, lifted and whole-tone — a charged dominant.

Harmonic function

An altered dominant. The sharp 5th strengthens the motion, often toward a minor or major target.

Typical progressions

  • G7#5 → C
  • Dm7 – G7#5 – Cmaj7
  • C – E7#5 – Am

Guitar voicing advice

Use a #5 instead of the 5th, ideally as the top voice. No perfect 5th needed.
