Chord & FretE7(#9) — dominant sharp ninth
Notes in E7(#9): E – G# – B – D – F##Formula: 1 – 3 – 5 – b7 – #9In the formula, the numbers count steps of the major scale starting from the note that names the chord; "b" lowers a half step, "#" raises one — and a slash names the bass note.
The 7(#9) layers the major third over the augmented ninth (the enharmonic of the minor third), creating an aggressive tension — the famous "Hendrix chord".
The same chord on all four instruments
Where to use it: Blues, rock and soul with an intense sound.
