This is a cool take! I don’t think I agree though. I assume we developed pattern recognition before music/language. Many animals have the ability to note attributes about plants and animals even without the ability to communicate complex ideas (ie language or oral tradition). I assume that type of pattern recognition was a good blueprint for functions like music and language, but my guess is it started from a general pattern recognition, then was retuned for music and language.

Again, pure speculation, but there is some logic behind it!
