Manooh and I have had all kinds of conversations about pi. Actually I wrote the song lyrics that I posted yesterday because she and I had been discussing the fact that pi contains, somewhere in its digits, all the melodies that have ever been written or ever will be written.

It’s true for poems too. For example if you write A as 01, B as 02, all the way up to Z as 26, space as 27 and so on for other punctuation, then any poem you can think of (as well as all the poems you can’t think of) will show up sooner or later as a string of digits in pi, if you go out far enough (2515212701180527031205220518). And if you write music as a string of digits, then you can also find all the melodies.

Manooh, quite rightly, felt that a song needs music. Since I had used the first thirty one digits for the lyrics of my little tribute to pi, she responded by using the digits immediately after those for the melody. The result was the following lovely song, which she promptly recorded and posted, and has now graciously given me permission to link to here, for your listening pleasure:
