Harmonics

[Srd2000]

Hello, is someone able to explain what harmonics, overtones and fundamentals of waves are in a musical sense? Feel free to get technical with the music theory too, I can handle it. Thank you

From a musical production background my understanding of overtones are basically any frequency greater than the fundamental frequency of a sound, harmonics are overtones except at specific intervals. If your fundamental frequency was at C2 (65.4 Hz), then an overtone/harmonic could be at G2 (98 Hz). Forgot to mention, fundamental frequencies are the lowest frequency of a periodic waveform. This is going a bit off-topic but if you are distorting a sound (where you are 'clipping' a waveform), you are essentially creating overtones based around the fundamental frequency (this is a common technique in dance music where you want a really full sound). This explanation is purely from a music production background and I haven't yet done 3/4 Physics but I hope I offered some help

In physics,  we look at harmonics as being standing waves. You count from having the smallest number of wavelengths up. The first standing wave that can be formed is the fundamental/1st harmonic. The second is the 1st overtone/2nd harmonic. The third is the 2nd overtone/3rd harmonic etc.
What standing waves can form depends on if it is in string/pipe and if 0/1/2 ends are fixed
