MATH, ART AND LIFE
Amorning of unusual mathematical connections, as part of the OttawaCarleton
Discrete Math Days
Featuring keynote speaker Prof. Jason Brown (Dalhousie University)
with live music accompaniment.
A HARD DAY'S MATH
Connections between Mathematics and Music
Abstract: 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 musical intervals
 circular seating arrangements, scales and rhythm guitar
 derivation of the blues and graph colourings
 the musical art of being ambiguous (or not)
 musical and mathematical transformations
I'll end off the talk with a discussion of some application of mathematics
I carried out on some musical mysteries surrounding The Beatles.
Yeah, Yeah, Yeah.

Jason I. Brown is a professor in the Department of Mathematics and
Statistics at Dalhousie University, and has written over 60 research
articles. His work that used mathematics to uncover mysteries surrounding
the music of the Beatles has garnered worldwide attention, including
national and international newspapers, CBC, BBC and NPR radio, Guitar
Player magazine, and the web sites of Wired and the Wall Street
Journal. His new book, "Our Days Are Numbered", explains
how mathematics can make life not only more interesting and meaningful,
but all of us more creative.
