How to Tune a Guitar with Harmonics: Part 1

Video Transcript

"So I have a guitar that is out of tune. So I have tuned one note. I have tuned my A to this metronome. Which every metronome has a built in A four-forty so that you can tune to it, or so you can tune your guitar to it. So every note or when you hear a note it is generally comprised of a bunch of different harmonic frequencies. Like this is a harmonic fifth fret. You just the string lightly, the fifth fret, and pluck it. You will get that sound. If you touch the string lightly on the seventh fret and pluck it, you get that sound. At the twelfth fret and pluck it, you get that sound. And there are other harmonics on a guitar. And when you put them all together you get a note that sounds like that. It happens to stand that the harmonic of the fifth fret of the low E string should sound the same as the harmonic of the seventh fret of the A string. So you can match harmonics. Those do not match so I tune my E string up to match my A string. And you can hear waves forming. When you get close you will start to hear waves in the sound that go wah, wah, wah kind of thing. Wah, wah, wah, wah. So as the waves get slower you are getting closer to matching frequences. Wah, wah, wah, wah. Alright, these are now in tune."
