GORHAM — The Southern Maine Symphony Orchestra, a University of Southern Maine School of Music ensemble under the direction of faculty member Robert Lehmann, will feature winners of the 2011-12 USM School of Music Concerto/Aria Competition at 2 p.m. Saturday, April 28, at Gorham Middle School, 106 Weeks Road. Tickets are $6 for the general public; $3 students, seniors, USM employees and alumni at the door.

School of Music students Aaron Pettengill, Derek Herzer, and Matthew Cloutier were selected through the competition to perform solos with the SMSO. Pettengill, of Lewiston and Saco, will perform the violin solo in Ravel’s Tzigane. Cloutier, of South Casco, will perform Grondahl’s Trombone Concerto.

Cloutier, a music performance major, was selected by the Portland Symphony Orchestra to receive their 2012 Martha Blood Scholarship, and will solo with the PSO at their May 7 youth concert. “I am really excited and humbled to be able to play with some of my teachers and other wonderful musicians in the area,” he said.
