Im abit confused about this. A chord is three or more notes (a triad) or more played at the same time right? The how could a power chord (the root and third) be a chord, unless you added the octave to it?
#2
Well, technically speaking it really isn't a chord. Just a root and a 5th. But I'm not really sure why it's actually considered one.
#5
It's considered a chord because it consists of multiple strings strummed together to produce a single sound.

Technically it's not actually a chord, but people say it is anyway. It's like the marshall MG of chords.

Great list Rutch. On re-reading this one I'd have to say Solid State means not liquid or gas.

I figured it out.

Yeah, really all it is is a root and a fifth combined, but a lot of times people will add that octave in there and make it a complete chord (1st, 5th, octave).

Its not a chord, Its a harmonic interval... or something like that.

They're not, it's something of a misnomer. They're really just intervals, but "power interval" sounds stupid.

That doesn't make it a chord, because it's still only two notes. A chord is three or more unique notes played simultaneously.

What about:

--7-
--5-

That is 3 notes now...

No, its still 2 notes. the 5th on the E string and 7th on the D string are the same notes, just an octave apart. It still only uses the notes A and E

True.

Interestingly, two notes can become a chord if you play them with "power". (actually distortion.)

There are 2 important types of distortion:

Harmonic Distortion (changing the shape of the waveform)

Intermodulation Distortion (heterodyning) This is the one we're interested in, atm.

Heterodyning is where the output of a non-linear system (such as an overdriven amplifier) will have the original frequencies AND the sums and differences of those frequencies.

For instance:

A4 440hz and a fifth above that E5 660hz on the input would result in:

660 - 440, 440, 660, 660 + 440 -or- 220, 440, 660, 1100

Back to note names: A3, A4, E5, C#5

So you have the root (and an octave below), third (placed up one octave), and the fifth.

You have a triad!

thats how i hold all my power chords...

otherwise its called a double stop.. which is just two notes at the same time

isn't it because it's just a shortened way of playing a barre chord? or am i wrong?

So E minor isn't really a chord?


Yes, but Em isn't a powerchord; powerchords explicitly contain only the root and fifth so that according to the dictionary definition of the term "chord" makes them not chords.

Why wouldn't it be?

Em:


--0--- E
--0--- B
--0--- G
--2--- E
--2--- B
--0--- E

Six notes. The set of italicized notes is the minor triad. The whole chord is EBEGBE, (1st, 5th, 1st, b3rd, 5th, 1st)

Em is a chord, power chords arent chords, even with the octave added, its just a name, and its really not a double stop either. power chords can't be major or minor, because it's just the root and fifth. to determine major or minor you need the third in the chord. so in summary, technically no, they are not chords, but us guitar players are just lazy and call them chords.
