A very close friend of mine is an accomplished improviser. After hearing a particularly stunning rendition, I’ll never forget his response to a question one of my colleagues asked him as to how he learned to improvise so well. He said that his first piano teacher insisted that he improvise a piece of music in response to every new piano composition he studied. He was brought up with the idea that music begets music. Consequently there was no division between presenting and re-presenting, between thinking up, in, and about.
