Why are there so many similarities in quantum mechanics and musical composition, incuding time relativity?
Everything is quantized, no matter how small the amount. The classic quantum pattern (a series of lines, first far away but gets closer and closer) applies to everything. If you look at a natural harmonic series, the notes start farther apart, and get closer together due to the “splitting” of the octave. I wouldn’t say that time relativity has a ton to do with it, since I’m not terribly into music myself, but quantum physics describes everything, not just things measured in angstroms and femtometers.
