- Learn about Difference tones (aka Beat Frequencies, “Tartini tones,” Heterodyne, under tones)
Fuzz and Distortion exaggerate these “difference tones” (the difference between two frequencies) which can make certain intervals sound out of tune. Power chords (4ths and 5ths) sound great, but a lot of other intervals can sound off which explains why some chords don’t sound good with fuzz and distortion. Playing with certain tone involves playing with great intonation.
Sure, the greats don’t need a calculator. Just a good set of hands and ears, however, learning the math is interesting and can be helpful. This could explain why the search for great difference-tone intonation tends to sound bluesy. This knowledge helps you sound good and play intervals with Fuzz and distortion "in tune"
If you'd like the pdf (or excel file) of the spreadsheet/calculator I made, here it is:

I thinking your cracking the DaVinci code of controlled feedback. Most of us use this instinctively but your getting it down to the math and science of it all. Like the harmonic systems, the dissonance difference system for controlled feedback.
Great Work!
As usual, this blew my mind. There's so much power in giving words (and understanding) to phenomena that we've noticed but never named. This may improve my playing, but I think the more important thing is that it'll improve my listening.
This is actually mind blowing, thanks gor sharing this knowledge and wisdom in a simpler and intuitive way, keep it up!
Noel Johnston every video you shed light upon some arcane corner of music theory.; fascinating, and the mathematics seems straight forward with this.
I doubt this is related, but this reminds me of those not so subtle undertones that arise when I mess around with ring modulation on guitar.
I like how you are so curious and overwhelmed with knowledge that you delve into tangents with the blues here; so human and fun despite the serious subject matter.
I'm glad I found you and I like your playing btw!
Thank you! Yes! Totally related. Ring modulators do indeed create difference tones. They generate a specific tone in the box and whatever note you play is as if you’re playing an interval.
I’m so glad I found this channel. Thank you for this upload in particular. I now know the name of that third descending note I hear when performing a unison bend upward. Fascinating subject. Unique channel. Stellar content, good sir.
Fascinating for sure! Thanks Noel
A lot of great stuff here on this channel. Cool!
This channel gives me serious KICKS
No it's beautiful that you can math it out and it's not just = numbers on a line it's actually number that convert to real life vibrations that we recognize!
Great lesson, bloody lots of UA-cam ads tho, hope you’re getting a cut of the $$$! Big hello from Sydney Australia;)
any thoughts on why you have 2 brass sadless and one in steel?
This was yet another awesome video. Thank you for sharing your insights, knowledge, and wisdom.
I might be mistaken but I think "normal" guitar isn't even tuned in 12 tone equal temperament. If I understand correctly, the "squiggly frets" produce actual 12-TET. I think those frets are called "true temperament frets". Seeing that you used charts for pitches, I assume you used frequencies of 12-TET. (As opposed to playing each note on guitar to tuner and writing down the actual frequencies your guitar produces.) In that case, your actual sounds were not exact frequencies given in the chart.
Anyway, that doesn't really matter. It's not important at all. I'm just being smartass and a nerd. In the end, one has to do what you said: listen and wiggle your notes.
Ring mod without the pedal
I hate to criticize and correct me if I'm wrong but I downloaded the file and started messing around with it I think you got all the pitches and frequencies right but I believe you misnamed the name for example G1 isn't 49 herts but G2 is so if you revise this it probably would save a lot of people headache and I still think the videos great just a small mistake in editing I was always taught low E on guitar falls on E2 of a piano and that's the Lowest note on a guitar.
Hey thanks for your comment. Trying to understand what you mean. Are you saying G1 isn’t 49 and should be labeled as G2?
On my chart, G1 is 49 (and is the low G on a bass), the lowest G on a guitar is G2 (which is 98). Are you saying that’s incorrect?
I do have E 82.41 (lowest note on a guitar) as E2 on that chart.
I also assumed he stopped at E1 because that's the lowest E on the guitar but it's not E2 is so that whole range screwed me up so I would play to notes with difference of E1 and it wouldn't harmonize right when I plucked an open string then I realized because everything was and octave low
@@nohjoh08 it could also just be my ignorance maybe he was doing it for bass players too 🤷♂️
All the frequency charts I have found have the lowest note on guitar labeled as E2 (82.ish Hertz). E1 is the low E on a bass.
@@nohjoh08 ok maybe he included E1 for bass and I was just assuming that's where he stopped because I assumed it was the range of guitar maybe he did the chart for a wider range than the guitar can play if you know what I mean it just confused me when I first looked at it
Nerd.
