The weekly rehearsals of the Haverford-Bryn Mawr College Chorale are known as a Wednesday night institution in bi-college life. The practices bring together students, faculty, staff, alumni and members of the local community in an oratorio choir of more than 100 singers. And each semester the Chorale, which is under the direction of Assistant Professor of Music Thomas Lloyd, gives a free public concert in Marshall Auditorium, accompanied by a chorale orchestra made up of advanced bi-college musicians and music students from the Curtis Institute and Temple University. This term, the Fall concert event (featuring 112 singers and 62 musicians) took place on Sunday, December 9, with a performance of Symphony of Psalms by Igor Stravinsky and Chichester Psalms by Leonard Bernstein.
