3 years in a row I came to this channel for last minute cramming and it's always these minutes long videos that gets me to understand the knowledge(and also, that I REALLY need to study hard when I'm supposed to) Thank you very much. XD
Sir, what do you mean by 'you can get all of these harmonics ontop of each other'. Do you mean that one plucked string can simultaneously play all these different harmonics? I mean, the basic idea of how standing waves happen (through interference of travelling waves) doesn't allow for that to happen. Can you please explain this misconception because I looked in a lot of places and no one is answering this specific questions. Right now, my interpretation is that 'skilled guitarists' know where to put there finger on the string in order to pluck it then generate the right harmonic, and they know how to do it very quickly.
I was confused too. I play cello and a harmonic to me has always been the softer octave that plays when you touch the middle of an open string. If you bow it and release your hand it slowly fades into the lower octave, but you can't play both at once. I guess if the sound was still in the air you could play both.
It's absolutely true : when you pluck a string on a guitar (or fiddle, or banjo or piano...) the string is emitting simultaneously all the possible harmonics : in fact, it is a multimodal emitter. BUT not all the harmonics are emitted with the same amplitude (or energy) ; in most cases, the harmonic #1 (called fundamental in Europe) is the most energetic of all and the energy decreases with the harmonic rank. The resonator (body of the instrument) selects some of the harmonics to be more amplified than others : that's the reason why guitars of different brands don't sound the same ; the most illustrative of my statement is given by resophonic guitars (Nationals or Dobros) : they over amplify some harmonics, (around the 1500-3000 Hz range), because of the presence of the aluminum cone inside the body... A guitar is a multimodal resonator, with a variable gain (amplification or damping) for each frequency ; the guitar player also does the same, when he changes the place he plucks the string (close to the bridge or close to the neck) : the percentage of higher harmonics will be modified !

Thank you very much. XD
I absolutely love how thorough and clear your teaching is, thank you for always including the relationships with formulas
Thank you so much for your videos, I always refer to them! I'm so lucky to have found your channel, I really am so grateful :)
U helped me a lot THANK U Mr.Anderson
I LOVE U
Thank you for taking the time to teach using visuals.
You explain it so well, thank you so much. Keep up the good work!
watched several videos about harmonics but didn't understand until your video! thank you for explaining it simply!
I LOVE YOU
You're my favorite professor
This is literally the most helpful thing ever
You are a great teacher! Thank you for the videos.
What a great teacher!
Very quick and helpful to do problem straight away. I really appreciate your videos
Who are those stupid guys who dislike this video ?!?! This is the best video you can ever find on RUclips .
man i love you i swere .. this was sooo helpful bozeman , keep up the good work
So your videos are super helpful! But is there a typo at 4:08 with the third harmonic shown with a sub of 2? I was sent a loop- Great Vid!

Your videos are pretty awesome.
thank you sir....i got much more understanding from your lectures....very helpful.....
Could have used this before my physics final last week!
Absolutely helpful. Thank you!
Ty Sir !
Thank you sir...i just got to understand it now
Thank you so much
Sir, can you please share the videos for different harmonics
he's amazing! !!!!
Would watch this video but Josiah's tree bush head is all in my face -_-
U r the best .....
I love u ^_^
I cant find myself
