Confusion about overtones and a slow-motion video of a plucked string

In addition to what Edward said: the waveshape in the image you posted is a graph of sound pressure over time, while the actual string in the video is a graph of string displacement over its length ...

Confusion about overtones and a slow-motion video of a plucked string

The Fourier transform allows us to decompose the shape of the string into a collection of sinusoids which correspond to the fundamental frequency and the (mostly) audible harmonics that give the note ...

Confusion about overtones and a slow-motion video of a plucked string

At a basic level, the waveshape in the image you posted is a graph of sound pressure over time, while the actual string in the video is a graph of string displacement over its length. The two are ...

Confusion about overtones and a slow-motion video of a plucked string

Disclaimer: I don't know the physics well, just combining what we see there with what we experience. The string in the video is plucked closer to one end than the other, much like a guitar or many ...

Confusion about overtones and a slow-motion video of a plucked string

The waves that we can see traveling along a resonating string are not the same as the waveform we hear when that same string is amplified. One major thing you’re missing is that the waveform pictured ...
