I can play a spontaneous and convincing harmony on my violin to any song I hear. Sometimes I can even do this as I’m hearing a new song for the first time and trying to join in. I also suck at reading sheet music, so this could be a survival adaptation?
Yeah. I think it started when I was playing 2nd violin in a community orchestra. I’d get lost and think just keep playing and look like you know what you’re doing. As long as it doesn’t clash…
Then I joined a band and they said there are no rules here. Make up whatever you want to go with the song. I was in Heaven!
One time, I was at some kind of open mic thing and an old guy walks up, introducing himself as the official city poet laureate. (Yes, that turned out to be legit!) He started reciting a poem about a local historic event and before you know it, I was playing along. He looked at me but continued. I think it sounded vaguely like something you might hear in a Ken Burns documentary, and when he was done, he came over.
Wow, that fit the words perfectly! What piece did you choose?
Oh what? No I just made it up on the spot.
Really! Could you play it again?
Yeah, no. But if someone made a recording, I’m sure I could harmonize to it! 👍
