Patrick Braga ’17 spent a little more than a year working on his chamber opera, “La Tricotea (Opus 25),” which will premiere Dec. 3 with 16 student vocalists and instrumentalists.“This was a project out of my own passion for composition and to convince people that opera doesn’t have to be a boring ordeal,” said Braga, who was inspired by a music history course with Professor Judith Peraino and a Glee Club selection by Assistant Professor Robert Isaacs.
