How do you keep track of a motif while improvising?
One of the things I find most difficult while improvising is keeping track of an idea, and developing it. If you improvise an idea off the cuff, how do you remember it?
Do you remember the entire melodic phrase, or do you only retain a rough sense of it?
Do you imagine notes on a stave?
How do you keep track of several improvised lines, and juxtapose them?
I find it very hard to keep track of something which I improvise and then build up on it. It is pretty much impossible for me to remember two or more separate improvised ideas at once. So,my improvisations end up being "mood pieces". Is this a bad thing, or does everyone do this to an extent?
