Yeah,but still.I mean,you understand the virtues of improvising,right?I think it just isn't the same thing.Try talking to your girlfriend face to face,then try writing her,you'll see it just isn't the same.
I heard,though,that Beethoven wrote some of his best works when he was deaf,and he'd conduct this huge thing and when it was over,one of the people in the orchestra would gesture to him to look at the crowd's reaction coz he couldn't hear it.
