(very little OT)

Comma is the word. The principle of commas is the base of occidental 
alterations (temperamento inequabile). An F# is a note 5/9 the distance 
measuring from the f to the g, while the Gb is a note 4/9 the distance 
measuring from the f to the g. This explains why a f double sharp is higer 
than a g (is 5/9 + 5/9 = 1/9 higher than g)
