After The Daily Beast published an article by Ted Gioia bemoaning the lack of musical theory in today's music criticism, a number of other critics and artists have been responding. One such response was the classically trained Owen Pallett of Final Fantasy Owen Pallett talking about the music theory behind Daft Punk's Get Lucky and Katy Perry's Teenage Dream. Update: he's now added a third and final essay to the series, and it's on Lady Gaga's Bad Romance.
