The choir will perform selections from its upcoming concert "The White Lily." A perusal of medieval Marian texts yields a long list of honorific names for Mary, the mother of Jesus, including "the white lily," "the shining star" and "the glorious mother of all." Songs and poems for Mary became so basic to medieval culture that they popped up everywhere: adopting the melodies of popular troubadour songs, inserted into pre-existing liturgical music and forming the basis of decidedly non-sacred love songs. This program of Marian music is a true cross-section of medieval music and a window into the medieval heart.

Formed in 1990, the Medieval Women's Choir studies and performs medieval music. It presents three concerts a year at different venues, including churches, synagogues and performance halls.
