What do you think double-stops are?

There are those who say it isn't a chord until you have 3 notes. I'm going to skip the complex music theory behind the arguments (I haven't studied them enough to understand much less form an opinion).

Of course in most music contexts there is more than one instrument playing and so the others can fill in the missing note making a full chord. Only a "one-man-band" really feels the loss.

Power chords only have two notes (although more than two octaves, I don't know if you count that)

		It's self-consistent: those who say that a chord must have at least 3 notes also say that power chords are not technically chords

		What do you mean about more than two octaves? The basic power chord is 3 notes, for example E2 + B2 + E3. One of those is an octave.

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
