If University of Baltimore Professor Roger Friskey’s brisk attitude and winning grin remind you of Robert Preston in the film classic The Music Man, in which, of course, Preston’s charming band leader character only pretends to teach teens to play their expensive instruments, cease the comparisons at cosmetic ones. Yes, Friskey’s teaching a brand-new songwriting class as part of the summer schedule at UB; true, Friskey encourages anyone and everyone to register, even those without a hint of musical training or ability. But the guitar-strumming, Renaissance businessman, who typically lectures on persuasive and public relations writing for the university, isn’t promising to turn his students into pop stars or producers overnight. He’s just saying all are welcome to join the lively workshop discussion of songwriting technique and the seminar chat about the fast-changing face of the music industry. And all are encouraged to compose at their level.
