Came out unplayable (except by a computer) and not so pleasing to the ears.

]]>(lower case = the lower octave = keys to the left)

(UPPER CASE = the next octave up = keys further right)

c C e E f F g G a A

This, assuming mapping starts at 0 gives the even numbers to the lower octave and the odd numbers to the higher octave and sounds very tuneful in places.

Does anyone have a link to a graph of the frequency of occurrence of digits in pi(to 10,000 places say)? Just by listening, I think there are more even numbers.

I think you are mistaken there, the effect you describe is ‘random + enough time’ but pi isn’t random. Unpredictable, but not random.

*AFAIK pi doesn’t necessarily go through every combination of number (in handy melody length groups).*

You’ll thank me.

Of course it’ll drive you nuts if you leave it running for too long… ]]>

If I’m remembering correctly, every finite string of digits occurs somewhere in the decimal representation of pi. So theoretically, if you plug all the notes of your favorite song into this thing, it will eventually play it for you. The problem being, of course, that it only uses the first 10,000 digits.

What we really need is a base 88 representation of pi, so that every key on the piano could get represented. Hook that up to a file with as much of pi in it as we know and let it run as some sort of audio art installation. Or, for a really insane version, make it a base 440 (5*88) representation. This way there would be enough digits to represent sixteenth, eighth, quarter, half, and whole notes. That way just about every melody you can play on a piano would eventually show up in it.

Or perhaps I’m taking this too far.
