There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

The Physics of Music, by Michael Ruiz, University of North Carolina, Ashvill
Using musical ear-training exercises, in conjunction with Lissajous figures, we will establish the simplest ratios for the frequencies of the major scale. We will call this scale the musician’s scale.
Then we will proceed to use strings and pipes to arrive at the harmonic series, which we will call the physicist’s scale. We will show how the I, V, and IV harmonies pervasive in Western music emerge naturally from our analyses with live piano performances in classical music and jazz.
