Wow, I didn't mean to start a problem (laughing) but this is the way I learned it in college. There are the only four or, arguably, five components of what we call "music." By "component" I mean those things from which music is made, without which, it ceases to be. By aspect, I mean those things which the components may form. And yes, these things must change, or the pickers don't go home at night, they keep playing the bagpipes, only God can make music without changing those four components (even James Brown has to stop the E9 chord to take Maceo to the bridge).

These are even more intrinsic than the color spectrum. You can't have a sound that does not contain these four, arguably five, components. All other aspects are made up of these four, arguably five, components. Even a single burst or cycle, in the real world, reverberates in its environment creating all four (arguably five, and in my opinion, sonance is part of timbre).

But hey, maybe I'm just riffing here. Prove me wrong.

All the Best,
Mike

You've got to know your limitations. I don't know what your limitations are. I found out what mine were when I was twelve. I found out that there weren't too many limitations, if I did it my way. -Johnny Cash
