Is no contest. I wish I was better at this. Not necessarily as good as John Williams, but … better. I started learning around 1994 or 1995, and then rather foolishly stopped, or that is to say, very wisely gave my priority to writing. So I could have been quite good by now, if I’d stuck at it. As it is I’ve probably even forgotten “Polly Wolly Doodle” and “Michael, row the boat ashore.”
However I can remember how to do my favourite chord, which is E minor and always makes me think of Ennio Morricone.
