Music with brutal and high variations of tempo and/or sound level and/or pitch
I try to give a hand to a friend who is preparing a talk about borderline personality in psychology.
Particularly, she was thinking to highlight the emotional distress and instability with some particular song with "some kind of peaks" in it.
The critical section would ideally last max 2-3 min, and maybe suggest huge joy, before to fall into deep and dark sadness very quickly, before to revert to another feeling with extremely high intensity.
To give an example, she had considered the final piano performance in '4 minutes' movie (but extracted from the movie, its emotional footprint was lower than expected). I have indicated classical music to set a tag to the question, but it is not required.
Any idea of music you've heard of, so that we should give it a try? Thanks
Certainly not classical, but your question led my mind directly to this track:
Stubb (A Dub) by Mr Bungle off of their self-titled debut album.
Mr. Bungle was an American experimental band from Eureka, California. The band was formed in 1985 while the members were still in high school, and was named after a 1950s children's educational film regarding bad habits which was later featured in a 1981 Pee-wee Herman HBO special... Mr. Bungle was known for its distinctive musical traits, often cycling through several musical genres within the course of a single song.
Well, I'm not sure it would make a suitable illustration for your friend, but it fits the description:
This song was created by artists Komar and Melamid and composer Dave Soldier in 1997 with the goal of including a wide range of elements that people, according to a survey, disliked in their music, including sudden changes of mood and tempo.
