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
