Too interesting to not pass on...

What a cool idee to do this.

Thanks Andy

So that's what music looks like, cool.

Pretty cool indeed. Do you think he's a Clapton fan by any chance?

I guess he might just have been, didn't do too badly although that thumb was way to prominent Lol Might be onto something as far as tuning goes though

It looks like a very cool idea for an album cover.

How cool was that?
But what did we just see? Was it necessary for the camera to be inside the guitar looking out... won't it be the same filmed from outside? And why are we seeing the sine wave? SLow mo? Any science buffs with an answer... where's Wrench?

How inquisitive you are, the force is within not without! You see it Mo Slow cos its Apple not Microsoft young Chris

It probably has to do with the field rate of the recording and playback.

PAL Interlace scanning at 50Hz on Uk tvs fills in all the gaps along with persistance of vision in the human eye and brain in normal circumstances. Phones will scan differently.

I have noticed this phenomenon for quite some time. If you hold your guitar in front of a television and sight across the strings, when you hit the string you should be able to see what appears to be a sine wave. At least it works on American cathode ray tube type televisions.

C'mon, where's the hard questions, Chris? Why do some of the waves look like two different strings?

Ah Dan, I just wanted answers not more questions... I am but a simple Jock!
Well I did notice that it was the lower strings which showed doubling of image not the higher so I guess that has to do with the over-tones being produced and the speed of the camera capture. The higher strings are vibrating too fast to be seen doubled?
Please don't speak to me in sine and cosines (my head hurts) but I do understand tones and overtones.

Mostly right, my friend, thereby completely blowing your cover as a simple jock! Note that I said mostly right. The higher strings are vibrating too strong, not too fast, to be seen doubled.

Don't speak in sines and cosines??!! Well, young man, I'll speak to you in the TONE necessary!


BTW, Tom, cabro, and Chris are all right. You can duplicate this phenomenon by watching your strings while playing in a darkened room with only the light of a TV screen or a strobe light.

vibrating too strong

... meaning the wave length is too short to show up?

Not the wavelength, but the amplitude. In the lower strings, the overtones are stronger than tones, so they appear on, or "overpower" the string that produces the fundamental tone. On the higher strings, the overtones have only a small fraction of the power of the fundamental tone, and therefore, insufficient power to mobilize the string. It may be helpful to note here that the overtones on the lower strings are initially powered physically by the string, then multiplied by resonance from the body. The power present in higher strings is minute compared to lower strings because of the smaller mass.

Yes, I mean amplitude.
Ok, the high strings tone is much stronger than its overtones ... so the overtones don't show up as they do with the lower strings where the overtones are stronger than the tone. Makes sense. Many thanks Dan, or may I call you Tech-Yoda .
