Carrie Semanco, a Butler High School graduate and member of the Butler County Symphony, offers some hints to violinist Shannon Waldenmeyer during a rehearsal session Saturday at the Butler Senior High School. Semanco, also a teacher at North Allegheny School District, is this year's string specialist for the Victor K. Phillips Creative Teaching Grant in the Fine Arts that is administered through the Golden Tornado Scholastic Foundation. The artist-in-residence program provides a professional musician to work with current musicians in the school district. About 90 students are participating in this year's program. A concert is then performed for the general public. This year's concert will be held Feb. 26. Times will be announced later.
