Chorus Novus is a 24-member Rochester-based choral group that specializes in singing a wide range of chant and liturgical music from the Catholic tradition.         The group was formed in 2002 with members from the former Sacred Heart Cathedral choir in Rochester, NY.    Directed by Terry Keach, Chorus Novus has sung at various liturgical events in the Rochester region, including an annual Advent or Epiphany "Lessons and Carols" at Our Lady of Victory and St. Anne churches in Rochester, and St. Mary's Church in Canandaigua, as well as a Tenebrae service at Our Lady of Victory Church in 2004.        Many of its members have performed for Pope John Paul II during a 1993 Rome Pilgrimage, and have sung at Our Lady Queen of the World Cathedral during a Montreal Pilgrimage in 1998. Chorus Novus is presently in residence at St. Anne Church in Rochester, and many of its members also sing in the St. Anne Church choir.
