How to use the E♭7♯9 chord

The E♭7♯9 chord is built from a root, a major third, a perfect fifth, a minor seventh and an augmented ninth. Start at the root E♭ and stack the intervals to get the whole chord: E♭, G, B♭, D♭ and F♯. The same formula gives you the chord in any other key.

Dominant seventh sharp nine chords drive funk, blues-rock and fusion as the tonic of a dominant-based vamp, not only as a V chord. Whole grooves in soul and rock guitar are built around this one chord.

How E♭7♯9 differs from similar chords

E♭7♯9 holds both a major third and a raised ninth that sounds like a minor third, so it is major and minor at once. That clash separates it from E♭7♭9, where the ninth is lowered, and from E♭9, where it is natural. Guitarists often call it the Hendrix chord.

Where E♭7♯9 is used

A dominant chord wants to resolve. Its home is the V of a major key - and the I of a blues, where the pull never lets up.

E♭7♯9 is the chord that wants to resolve, so ending the loop on it hands straight back to the top.
