I understand from reading on the net in the past regarding the Harmonics on a guitar, that the string vibrates in different sections along its length when plucked.

So my understanding is (could well be wrong that the Harmonics for a C note would be E and G)

So just wondering for anyone here who has gone into the very technical side of things, does that mean that when you pluck for example the C on the third fret of the fifth string on a guitar that the C is sounded, but in fact the E and G are played Harmonic wise as well but we don't really hear those Harmonic Overtones due to the loudness of the fundamental C note?

If the above is correct wouldn't that be a good way of understanding why the chord of C major with its C E and G sound so nice together?

Or am I totally wrong here?
A very interesting question, I don't think you are wrong and Levitin addresses some of this.

When you listen to a single note played on an instrument, you’re actually hearing many, many pitches at once, not a single pitch. Most of us are not aware of this consciously, although some people can train themselves to hear this. The one with the slowest vibration rate – the one lowest pitch – is referred to as the fundamental frequency, and others are collectively call overtones.

Surprisingly, these other frequencies are often mathematically related to each other in a very simple way: as integer multiples of one another. So if you pluck a string and its lowest fundamental frequency is 100 Hz, the other frequencies will be 2x100 (200 Hz), 3x100 (300 Hz), etc.


Where this might not happen is when you play a pure sinusoidal tone/note on a synth.

For me there’s no better place in the band than to have one leg in the harmony world and the other in the percussive. Thank you Paul Tutmarc and Leo Fender.
