Nicely done! A very basic and simple introduction which explains things I didn't know needed explaining until I heard them here. A few problems with the overdub balance at certain points but overall, very impressive as a first introduction.
A lot of the sound of the guitar comes directly off the top, because the string vibrating against the bridge vibrates the top, making it act rather like a speaker cone. Some of the energy comes off the back of the top, into the body of the guitar, and some of that energy comes out the soundhole. The "back wave" off the back of the top is 180 degrees out of phase with the "front wave" (direct sound of the top) and is ported out the soundhole, but is slightly delayed by having a longer path (via the hole) to the listener, somewhat like the bass port of a ported speaker.
Using this video, some people have have ideas to resonance of bidirectional hole, amplification circle, _____ bigger circle, ... to subwoofer placement. Same shape as violin and ...
Ironic-perhaps not the right word- that waveforms are presented in an educational context, yet the video's audio isn't mixed correctly. Otherwise, a great educational topic and good enough for learning purposes, even though I had to strain to hear past the various parts where music was being played, just to hear what was being said.
Too basic, except for the fact that humidity changes the sound. Some sort of complex schlieren flow visualization in a big guitar might give a better understanding. Sounds have to be the hardest quantum physic subject
Good summary, but the acoustic guitar can’t amplify sounds. It conducts them from the strings to the sound board, where the vibrations can move more air.
@@zk2611 No, it's more efficient transmission, which is different from amplification. Since it's not actually amplified, making it move air more efficiently also reduces sustain, because the limited energy of the vibrating string is more rapidly depleted. Amplification lets you use only a little energy from the vibrating string to generate a weak signal, then amplify the signal electrically, without robbing the string of energy nearly as rapidly. Just adding mass and rigidity to the bridge will make transmission of energy to the guitar's top, and reduce volume but increase sustain. (People do that with archtop jazz guitars, replacing wooden bridges with somewhat heavier and much more rigid metal ones to get more sustain.)
This is a basic level explanation video, I'd say it explains things at the perfect level for their goal. If you think you could do better then make your own video.

lol but how did Einstein sneak his way into this one with a mere silly quote?

Yes! This is the exact video explanation I've been looking for. Thank you!
can you tell me..from which book the visuals are from ??
This is an excellent lesson that every guitarist ( like me) should see
Brian May Master of guitars and astrophysics :D

Neat video
Very nice I sub ;)

That is amplification, by definition

Y the dislikes
I think the parts like these 2:17

Nothing new, everything you say is quite obvious
