Go to the full guitar chords tutorial.
Built on F, the F7#9 chord (F seventh sharp nine) combines a root, a major third, a perfect fifth, a minor seventh and a sharp ninth, which gives F, A, C, Eb and G#. It is a dominant seventh with one altered tone, the raised ninth G#, and it is often called the Hendrix chord.
Four voicings in total, from fret 1 to fret 9, and one of them is a barre shape. For melodies, reach for the F Half-Whole scale: it is the eight-note scale built from alternating half steps and whole steps, and it holds all five chord tones.
The fretboard at the top labels every note of each shape, so you can see where F, A and G# fall.
F 7th with sharp 9th guitar chord is also written as F7(#9), F7#9 or F7+9. It is also known as the Hendrix chord.
