So what is it about improvisation that is unlike other forms of musical expression? Unlike Karaoke singers and Orchestral musicians and even Cover bands where it takes zero talent (skill, yes. Talent & creativity, no) and opposed to the standard songs all over the radio and most-recorded songs in the studio where every note, every bar and measure is thought-out and decided upon (why aren’t there more hit songs when you have as much time as you want to create the hooks?) … improvisation is an entirely different beast in that there is no time to think it through.
Lose yourself in the moment, cast a line, return home from time-to-time, don’t think too much but be aware of the picture you are painting. Listen to the entire room, not just to yourself! Don’t be afraid to make a mistake and don’t be afraid to experiment.
It’s like driving a car on an unknown road at night when you can only see as far as your headlights show. Are you afraid to go on, not a chance because you know how to drive. When you’re improvising, it’s that same confidence and that same curiosity of what’s coming next that will have yourself amazed at the results.
