You might already have realised that I like discovering interesting ways to make music (which is why the HARP appealed to me), so this “instrument” based on lunar topographical data sparked my interest.
Yes, it’s a fairly bizarre concept — take data from Japan’s Kaguya explorer as it orbited the moon between 2007 and 2009 and then assign musical notes and instruments to that data.
Sadly, it’s a Java applet (sorry, I have a thing about avoiding Java unless it’s absolutely necessary) but it’s still definitely worth a look. You can tweak a number of parameters to get the sort of effect you want.
It’s not going to make it in to the charts, but then I generally don’t like chart music, so that’s a good thing.
