I certainly don't have the pitch detecting skills that this muscian has. And if I think about it, maybe having such skills is a curse because everywhere you go you probably hear music out of pitch. I'm guessing that would be annoying.

For grins I recorded and analyzed a single C note on my bass guitar. My error compared to the theoretical value is approx. 8.2% even though my clip-on tuner told be I had a solid “C note”.

There are a few computational things I could do to reduce this error. But I’m too busy at the present time. Nonetheless, this exercise illustrates what the YouTuber was saying regarding overtones.

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.
