Whimpy-ass chords. You need three or more notes for a serious(tm) chord.

Five for the Hendrix Chord, E7♯9 ;-)

That's E, G♯, B, D, F

Every jazz player knows you can drop the fifth, and the root too if the bass is filling it in. That gives your fingers room to add even crazier extensions

Oh man have you seen the Adam Neely video "Seven Level of Jazz Harmony"?

If not, stop and watch it. But make a cup of tea to enjoy with it first, and maybe put a cloth over your keyboard for when you inevitably splutter tea all over it.

I read a pretty good argument once that this chord should really be called a b10 (no one does though...)
