Raised on the Rolling Stones, most don't know a fugue from a rondo. But harried by rush hours or by boisterous kids, they adore classical music as a sort of sonic Valium. They like the fact that classical music can be calm and soothing. The music was then grouped into like-sounding clusters, called modes, using a statistical technique called factor analysis. You can't play everything in the repertoire and expect to have an audience.
Violin is taboo.
Anthony Rudel eschewed research and used his own system when programming for the recently defunct classical-music division of Sony Worldwide Networks. On SW Classical, potentially grating offerings like solo violin were taboo. People don't want radio to be invasive. That doesn't create an appreciation for the art form. And that means playing more than just pleasant Baroque trumpet concertos or the slow movements of Mozart symphonies.
