More principles of contemporary classical improvisation:
When you hear a good idea (from yourself or from someone else) while improvising, support it or relate to it in some way – just as you would in a good conversation with someone.
Creating music is not about right note/wrong note – it’s about imagination.
Silence is a very important part of making interesting music. Don’t forget not to play.
Practice with a partner as often as possible. A partner can challenge, inspire you, give you energy and motivation, and make you want to ‘show up’ and play more.
