The Greek philosopher Pythagoras was obsessed with music and math, and considered them to be two related forms of the language of God. Today we'll look at some resources that explore music and math.

1) Let's start with Pythagoras himself. This science video explains how Pythagoras related music, math, and mysticism (you might miss it at the end when the host mentions how Pythagoras believed the principle of number ruled everything in the universe).

2) This kids' science article discusses musical composition using pi and fractals. The article mentions Swedish composer Daniel Cummerow, whose pi works can be found on this website (scroll down to the fifth sound file for the one the article mentions) with some other aural representations of that famous number.

3) On the physics side of things, this software website has a surprisingly good article illustrating how math can describe "good" sounds and "bad" sounds. It explains the phenomenon that Pythagoras found in a little more (scientific) detail.

4) And, the article that spawned those "Baby Mozart" videos, except it really describes an actual phenomenon: researchers found that listening to a Mozart piece raised intelligence on the order of 8 or 9 IQ points. You can check out the full text of their article here. However, this research is highly contested and these results have not been repeated (as far as I know!). Why not just use music and math to raise your kids' IQ the old-fashioned way?
