When we initially started this blog, we aimed to discuss, among other things, what exactly constitutes "good music." This idea has always seemed highly elusive to me, perhaps because what I think of as "good music" is itself elusive.
Really fantastic music doesn't fit a recipe or mold, and although it often meets certain expectations and most likely feels inevitable, it also surprises its audience with freshness. The day after the concert, usually you can still hear "good music" in your head--not because it's repetitive or catchy necessarily, but because the sounds have left a tangible impression. This is my best effort at offering some sort of definitive classification. Perhaps its vagueness is appropriate, as the definition can be applicable to all kinds of music, not just "art music."
