yeah, this is more a lesson in the weird things the iphone camera does rather than guitar strings. posted by GuyZero at 3:27 PM on July 14, 2011
It's like a strobe light. It does demonstrate the wave in the string, but it's not exactly a standing wave or an accurate representation of the waveform, and it's definitely not slow motion, you could make the wave change shape or move backwards if you adjusted the refresh rate, probably. posted by empath at 3:32 PM on July 14, 2011 [1 favorite]
wonder if the iphone could capture this. (1:20) {28 notes a second}
neat video and nice playing. posted by clavdivs at 3:33 PM on July 14, 2011
Admittedly it's much less visually interesting, but is much more accurate. As you can see there is a very slight "wobble" to a guitar string when it's plucked away from the center, exactly in the same way you can induce a traveling wave in a taut rope or cable - but it's very subtle and doesn't look at all like the iPhone video. The bulk of the movement in the oscillation in a plucked string happens at the midpoint of the string, which is halfway the distance from where the string is being fingered on the frets and the frog at the base of the guitar. posted by loquacious at 3:40 PM on July 14, 2011

So Blazecock, an image taken with an iPhone is really like a composite of many smaller individual frames? posted by MattMangels at 9:51 PM on July 14, 2011
