Trifles , a chamber opera in one act, premiered in Berkeley, California , at the Live Oak Theatre on June 17 and 19, 2010. It was composed by John G. Bilotta, and its libretto was written by John F. McGrew. The chamber opera is scored for five singers and six instruments , including a piano, and it requires some basic stage props. As in the play, the central figures (Mr. and Mrs. Wright) are absent from the cast of characters. Instead, through the libretto, Lewis Hale reenacts the events surrounding the discovery of Mr. Wright's murder, where he was present.
While the men are investigating upstairs, Mrs. Hale reminisces about how happy Mrs. Wright had been before her marriage, and she regrets that she had not come to visit Mrs. Wright despite suspecting the unhappiness she had suffered as John Wright's wife. After looking around the room, the women discover a quilt and decide to bring it with them, although the men tease them for pondering about the quilt as they briefly enter the room before going to inspect the barn. Meanwhile, the women discover an empty birdcage and eventually find the dead bird in a box in Mrs. Wright's sewing basket while they are searching for materials for the quilt. The bird has been strangled in the same manner as John Wright. Although Mrs. Peters is hesitant to flout the men, who are only following the law, she and Mrs. Hale decide to hide the evidence, and the men are unable to find any clinching evidence that will prevent her from being acquitted by a future jury - which will, the play implies, most likely prove sympathetic to women.
