Harmony 'driven by mathematical ratios' - The Irish Times - Mon, Jul 16, 2012: "It was apparent to mathematicians going back to Ancient Greece that musical harmony was fundamentally driven by mathematical ratios.
The public are generally unaware that the ‘three chords trick’ which is the basis of all popular music is an idea going back to the father of geometry Pythagoras.
The Greeks established that the first note in the scale and the fourth and fifth are the most harmonious together and they are governed by ratios.
For instance a standard A has a pitch of 440hz, the fourth note a D has a pitch which is three-quarters of that at 330hz and the E note or fifth is two-thirds of the pitch of the A at 293.33hz. The higher A at the end of the octave is at 220hz half that of the lower A.
The ratios remain as important today as they were in Greek times."
