>>13228367Jazz and classical musician here. These are the two genres that are usually recognized as the most academically established due to their complexity and dense history.
Different genres place emphasis on different metrics so there's no such thing as "perfect" music.
Classical is highly structured and is mainly used to tell narratives that make use of very straightforward and powerful chords to form easy to digest soundscapes. Post-baroque classical is more or less your big blockbuster movie in sound form. Anyone can enjoy it and it does it's job incredibly well. Of course you have exceptions such as satie, scriabin, and schoenberg.
Jazz is an entirely different beast as it takes various conventions from classical and blues, and mixes them in a highly abstract manner. Almost everything in jazz is able to be used to creative effect as there are few rules. It's also generally improvised. Your average pleb probably isn't used to listening for unorthodox chord changes, 9th 11th and 13th chords, or time signature changes mid song. By the late 20th century some forms of jazz had become so complex that listening to them became a skill in itself. (Look up allan holdsworth's stuff)
