Mathematics and Music

Mathematics and music are a match made in heaven. The ancient Greeks elevated both to the same level, and even the most unschooled rock musician uses more mathematics than he or she realizes. In this talk I'll survey some of the most interesting connections between mathematics and music, including:
- trigonometric identities and tunings
- small fractions and intervals
- circular seating arrangements, scales and rhythm guitar
- Joni Mitchell's capo system
- derivation of the blues
- the musical art of being ambiguous (or not)
- musical and mathematical transformations
I'll end off the talk with a discussion of an application of mathematics I carried out a few years ago to two musical mysteries surrounding The Beatles.
