Natural or instrumental sounds usually consist of complex harmonic structure. In this post I’ll try to explore basics of human pitch perception.
According to wikipedia: “Pitch represents the perceived fundamental frequency of a sound”.

Below you can find a recording of the sample repeated four times, each time followed by a single successive harmonic:
