To play G♯13 on piano, place your right hand with your thumb on G♯, index finger on B♯, middle finger on E♯, ring finger on F♯ and little finger on A♯. Press the keys together and listen for an even sound. On the keyboard G♯, F♯ and A♯ are black keys and B♯ and E♯ are white, the keys you'd normally call C and F. The thumb starts on a black key, so slide the whole hand a little further in, towards the fallboard. Practice moving in and out of the chord slowly, then bring in a metronome.

How to use the G♯13 chord

The G♯13 chord is built from a root, a major third, a minor seventh, a major ninth and a major thirteenth. Start at the root G♯ and stack the intervals to get the whole chord: G♯, B♯, F♯, A♯ and E♯. The same formula gives you the chord in any other key.

Dominant thirteenth chords are the default rich dominant in jazz, gospel and R&B horn and keyboard voicings, usually the V7 resolving to a major or minor tonic. Big band charts lean on them wherever a plain dominant seventh would sound thin.

How G♯13 differs from similar chords

G♯13 tops the dominant family, with a thirteenth over G♯7 and G♯9. The thirteenth is the sixth an octave higher, and that is the line between it and G♯6: G♯13 also has the minor seventh, so it keeps the dominant pull. The fifth and the eleventh are left out so the voicing doesn't get muddy.

Where G♯13 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.

G♯13 is the chord that wants to resolve, so ending the loop on it hands straight back to the top.
