Dave, I agree with what you said anyway, and was originally only referring to something like jazz that in a way has no idea until it is performed (at least jamming type jazz as opposed to charts). Though something made me think about how a so-called "musical idea" is actually a mental projection of a performance.
Though I have the same experience as jbm - I wonder about that, isn't it a function of time in the composition process? In other words, when you first have an "idea" - what is it? Actual notes or sounds? Sometimes not - it is more a feeling that there is something that can be developed.
