Amazing, the Female voice has more bass harmonics than the Male. Also, you see the Male has very close fundamental frequencies where the Female has a more pronounced fundamental (of course) at a higher frequency. Very interesting.
@LinkEX9 жыл бұрын
7:29 Wait, I thought the fundamental that determines the pitch we perceive was the loudest? But regarding the trombone, it looks like the harmonic of 660 Hz is the loudest, and for the clarinet the one at 440 Hz. How come the loudest frequency isn't perceived as the dominant one in those instruments? What determines the perceived frequency in a timbre then, if not the part with the highest amplitude?

@user-mg7le8rp9u8 жыл бұрын
+LinkEX I had a same question and here what i found on wikipedia about it: "The lowest frequency is called the fundamental frequency, and the pitch it produces is used to name the note, but the fundamental frequency is not always the dominant frequency." en.wikipedia.org/wiki/Timbre#Harmonics So, not the loudest frequency determines the pitch, but the leftmost one. And all charts at 7:29 have the same lowest/leftmost frequency - 220 hertz.
@LinkEX8 жыл бұрын
Тра тата Thanks for letting me know what you found out! The way Wikipedia describes it still leaves me wondering, however, what it is that determines the factor one has to choose to get the dominant frequency from the fundamental one then. (As example they liste the traverse flute having the factor 2, but not why that is.)
@josefenrenfest17618 жыл бұрын
If a wavefunction's frequency is f, then it can be expressed as a superposition of sinewaves with frefuency f, 2f, 3f, etc. The biggest question that bothers me is that for a period function, its fourier transform in a continuous domain is supposed to be a superposition of different dirac delta functions; but in the video and many other audio processing softwares, the fourier transform doesn't blow up to infinities at all.

Thanks, I finally understood the relationship between pure waves and the complex waves produced by an instrument. Not really interested in music, but in quantum mechanics. Do musicians realize the link with vibrating electrons?
@VeronicaGorositoMusic5 жыл бұрын
Slowly, but yes, more tech channels on YT made me understand how EM field had to be with colors and sounds. I think my interest started when looking for a tube amp, and why. Some say tubes are better, but I needed to know why. Then learned about electron flow in the grid...and it all started :) I guess my dad being in the Army helped to have a friend who understood very well about waves and radiation because he was radio operator in the 40's and they used valve gear and all the nuclear fission was in people's mouths. He shared me lots of anecdotical data from those years, and the tech advancements, and I tried to link it with music but didn't get it really. It took me like 10 years to see something, and then slowly my mindset was resetting! I was still having religious ideas... SciShow, PBS Eons, are cool channels and more and more they are getting public attention and more youngsters are interested in science in general, but myself, from being totally ignorant, to start to understand why the strings of my guitars make sound, leaded me to learn about superconductivity and neuroscience and quantum mechanics, made me more aware of what music is, and how Einstein was the real deal of geniuses. Everything is linked and when you start to getting deep in the research, life becomes amazing. And weird !! Not that I understand all this, but get the basic concepts of why when you clap, your hands get warm, according to Feynman lectures :) Too much to learn still...but I wish more people not only musicians learn the physics of everyday's life.

Do the harmonics of the clarinet, trombone and cello include other octaves of the same pitch, or A in this case? Initially I thought the harmonics include other pitches but then I thought my initial assumption doesnt make sense. Could anyone please confirm? Thanks

It is explained in the following video. But they are not all the same note, one is the dominant note in the A scale as well as the mediant and 7th harmonic.
@PhilBusby4 жыл бұрын
At 5:20 you said (correctly) that the fundamental is the lowest and the tallest, but at 6:20 you show a trombone waveform where it is not. Nowhere do you mention the each harmonic is given a specific name 2nd harmonic (at twice the frequency of the fundamental), the 3rd harmonic (3x), the 4th harmonic (4x) and on. Some instruments can have over 30 harmonics, all descending amplitude and often not included in some synthesizers which makes the real instrument sound so much better.

See in 3D?? You are not showing the waves in 3D, you are showing the frequency spectrum in 3D, which is a whole other thing and a concept you demonstrate not to grasp. I also believe that this analysis should've been made in 2D since 3D only impairs one's correct perception of distance between frequencies.
