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.
Jazz is my favorite genre to play- this thinking sill applies but it’s a lot more abstract- even if there is heavy improv as is the style, it’s still musical patterns over repeating chord changes. Couple that with the subversion of expectation thing I mentioned elsewhere in this thread and it’s a winning formula if I’ve ever heard one.
That’s why I like comedy and soulslikes. The subversion of expectations 😃
