What constitutes good music? I remember music appreciation courses that might have made me hate music forever if I had not had the good fortune to hear it in so many other places.
Asking what good music is reminds me of a song whos words I can't remember, lol. I remember the tune and the timing. It was an upbeat little thing, maybe from a musical that went "To a ______, it's a __ __ __." And goes on to mention others who find similar things.
So typical of me anymore, but the idea is that good music absolutely depends on who you ask. Whether it is classical, or rock, or indie, or opera, or ragtime, or folk, or heavy metal, or whatever, people are picky about their music.
I find music written and sung by the same person, personally and IN person, the most beautiful music of all. It's like someone baring a bit of their soul in ways no one else possibly could.
After that it is music that moves my soul in some emotional way, whether that is haunting, or stirring, or evoking some picture that touches my deepest sense of belonging. It can be anything from Mozart's variations
Ah, vous dirai-je, Maman (which sounds like Twinkle twinkle little star, to Sousa's marches, Celtic folk music, Nessun Dorma from Puccini's opera, Turandot, to many popular songs from the radio.
I admit I am common by music snob standards. I love John Williams' music. It lifts me into realms I find many other composers miss. I love Jerry Bock and Andrew Lloyd Weber and others I cannot think of right now.
Which of these, beyond the personal musicians do I love best? That totally depends on the hour.
