Moazrt literally grew up improvising. He was taken on a tour of Europe when he was ten, and he'd improvise fugues and arrangements with a blindfold on, or the keyboard covered with felt so he couldn't see the keys.

The tour was a double act with his sister who was only a few years older - rated a much better performer, but not such a creative improviser.

He'd have been horrified by the modern idea of 'Here's the piece, these are the notes, play it exactly as it's written or we shoot you.'
