Music is just layered simple patterns and our brains LOVE IT.
Sound is pressure waves, musical notes are a specific pattern of pressure waves. Melodies are repeated musical notes. Songs are repeated melodies following standard structure.
Our brains love trying to decode and parse all these overlapping patterns.
Maybe not really a shower thought and more wild speculation.
I think this is getting it backwards. Here I’ll go (warning, evopsych style speculation follows):
Our brains are great pattern recognizers because it makes us better at learning music (and other structured forms such as poetry). Music is older than all the civilizations on earth. We learn music because it’s an incredibly powerful aid to memorization. Memorization and oral recitation is the oldest form of cultural transmission we have.
Culture is the secret of our success as a species. It’s the original problem solver that gave us so many tools and techniques to survive on every continent on the planet (except Antarctica of course). Culture is the reason we learned to prepare so many foods which would have been poisonous otherwise (such as cassava).
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!
