If I had never improvised before - I would try playing a piece that I really like - and then begin playing it a little different - (just a little) Are you enjoying it? Change it a little more - I would say make every change small - so your focus is on enjoying the music - and the sound.Why don't you try it Bob? Substitute a few chords - take out the melody but keep returning to the chord on a chord change and little by little you may find you can do it.
Improvisors and composers can't musically create anything they haven't already heard. They simply use the micro-ideas of music they've heard before and create new sequences of them according to their own taste.
I don't believe that at all. I think most here would reject that notion.
music comes from and touches the inner ear, not a thinking part of the brain.
Musical language isn't theory...since music technically means nothing, study of theory is an attempt to gain intellectual grasp of something sensual. It has it's importance, and can be interesting, but music comes from and touches the inner ear, not a thinking part of the brain.
Music Theory is the means through which that raw concept is displayed. If we didn't have chord structures and scale degrees, and specific sounds and relations, we wouldn't have music.
I haven't much, if anything, with improvising. How do you do it? What do you think of/focus on? How do you learn it? Learn by doing, yes, b ut is there a standard path?
I'm sure there are... but are there any other types? I've heard of, but don't know anyone, who improvises contrapuntally.
