Dr. Diana Wagner, a Salisbury University professor, gave a master class for 6th grade guitar students at Berlin Intermediate School.  Students learned special techniques for strumming and using guitar picks as well as playing the blues style of music.  The guitar students also attended a field trip to In Tune Guitar Picks in Onancock, Va. to learn how guitar picks are made.  The guitar students are instructed by Lisa Adams, BIS music teacher.
