### Why does playing a string instrument at different positions along the string cause different sounds? [duplicate]

While playing with a violin with my friend, they told me plucking at just any position will produce the "wrong" sound, and to achieve the sound desired for the piece you must pluck at a specific point ...

### Are square wave harmonics real-life phenomena or just mathematical abstractions?

Based on my limited knowledge, it is my understanding that square waves can be mathematically broken down into an infinite sum of sinusoidal waves (of different amplitudes, frequency, etc) . This is ...

### Why are the harmonics on a string controlled by where we pluck it?

I just read this answer by rob on the question of why harmonics occur when plucking the string, in the answer I have a doubt on this point: It's worth pointing out that you have some control over ...
