But what does a sorting algorithm sound like?

The visualizations linked there are great too:

Great start. You could definitely get a more musical sound out of it by mapping it onto a scale rather than just the full range of MIDI notes. Also, this approach operates on fixed note lengths--another interesting idea might be to use one of the compared numbers to determine note length rather than a second pitch.

I can't wait for the first array that will sound like the mario tune when sorted. Kudos to the creater if a different algorithm will create another song

And so now, thanks to this, we have the answer... it sounds like an old NES RPG.

That is amazing!

Great idea.

Very cool.
