Pettry said it will be the first public performance of the complete work. Excerpts have been well-received. Pettry wrote an orchestral arrangement of the piece's second movement, which recently won Shepherd College's composer's competition.
Eventually, Pettry will orchestrate the entire piece and will publish the work. He said the requiem is an attempt to capture the feelings in the aftermath of the terrorist attacks.
"I didn't want to recreate what happened on Sept. 11, but I did want to capture that mood of uncertainty of fear," he said. After a somber and sorrowful beginning, he said, the piece moves through fear and anger before ending on a more hopeful note.
Pettry said the four-month writing process helped him come to grips with his own feelings about Sept. 11.
