Mozart's Requiem

Mystery and myth surround Mozart’s Requiem.  It was left uncompleted at the composer’s somewhat sudden death, and no one quite knows exactly how much music he left behind.  His widow, Constanze, was set with the task of finding another composer to complete the work, while still promoting it as a Mozart composition (in order to receive the full commission fee).  After Joseph Eyeler, one of Mozart’s students, was unable to complete the Requiem, Franz Xaver Süssmayr, another former student, finally completed a working version, which stands as the most popular of the many versions still performed today.
