A few days ago I got a shiny new MacBook Pro. I’m usually monomacous, so it’s the first time in four years that I’ve had two Macs at the same time. This had me wondering what to do with them, and one of the first ideas was to have them sing a duet. Of course, it’s easy enough to get a single Mac to sing something twice in different voices and then edit them together (as I did with You’ve gotta be happy), but with two Macs I could make a somewhat interesting video. A friend of mine suggested it would be good to do a round, and I agreed.

While I was still thinking about which round to get them to sing, I saw a link to this article, showing a video of three robots humming happy birthday to the London Science Museum. They’re a lot more sophisticated than my own ‘robot choir’, having actually learnt to sing together, but nonetheless I decided to get my Macs to sing it too. Here is the result:

It was easy enough; a short song with music available. I think I spent the most time deciding on appropriate desktop pictures for my Macs to wear on stage. The other challenge was tapping ‘Start Speaking’ at the same time on both computers. As you can hear, I didn’t quite manage it the first time around. I could have done it automatically, with a script starting it on both computers at a given time, but then the video would have been essentially two unchanging computer screens with some singing in the background. This is a ‘live’ performance, and dalrymples are obligatory.

Audio of the successful attempt will soon be available on the podcast.

Update: You can now make your own Mac sing this.
