As much as the next person, I always love music to have a strong emotional output. This is subjective from person to person, and our opinions differ - but I think a lot of people dont realize that music can be completely and utterly devoid of emotion (in the writers eye at least) and still be music. I realized this only recently when I was reading some articles on classical music and it listed how many famous compositions were actually music essays, studies in technique and theory - and nothing more.
While I believe this to still be music, I think this actually supports the subjectivity of emotion in music - because some of these pieces are hailed as some of the most beautiful ever, yet to the composer they were an exploration of technique, theory, or maybe even curiosity?
Just a thought I have had for awhile, anyone care to chime in?
