is there a field of study about like, the effect od time periods on music? like no yeah not the tempo necessarily, that's kind of like how we separate time periods into their own kind of genre. like 90s rock or classical compisers.
but like, a comparison between the 70s musical choices for Willy Wonka vs. modern 2023 Wonka. the lyrical choices, the timing on the songs, the themes, repetition, and situations they choose to go into song (in the case of a musical where plot affects all of these)
how about popular instruments in certain countries and time periods? any focus on certain romanticism, somber or slow music, drinking songs, chants for revolt, hidden meanings for certain political periods? that kind of stuff
