[ani-ani]

This is a fun exploration, though there's a lot of fuzzy usage of terms and missing stuff. Eg. the first 5 paragraphs are apparently trying to define timbre, yet the word appears nowhere. Same with harmonics, etc.

I think one of the most interesting things about pitch is that it's not well defined, it's a psychological phenomenon. If you could extract it from people's brains, you would likely get different values from different people. This is compounded by the fact that harmonics produced by real instruments are not exact ratios of each other, yet they affect the perceived pitch.
