A televised concert in Sanders Theatre and an appearance with the Boston Symphony Orchestra at Tanglewood will highlight the activities of the 300-member Harvard Summer School Chorus this season.
The Sanders concert, to be broadcast locally on August 15 by WGBH-TV, will include works by Schuts, Byrd, Janequin, Barber and Bach. The Chorus, under the direction of Iva Dee Hiatt, associate Josquin, this concert will be sung on professor of Music and director of choral music at Smith College, will be accompanied by a chamber orchestra drawn from the Cambridge Civic Symphony.
The first rehearsal of the Summer School Chorus will take place tomorrow at 7 p.m. In Sever 11. All registered students are ellgible for membership.
At Tanglewood the Chorus will sing the Mozart Requiem in honor of Pope John XXIII with the Boston Symphony Orchestra under Eric Leinsdorf on July 14.
A smaller concert of medieval and renaissance music will precede the Sanders performance. With a program of music by Machaut, Dunstable, Dufay and July 24 in the Busch-Reisinger Museum.
Miss Hiatt has planned the August 15 Sanders concert to display the range of vocal possibilities of a large, mixed chorus. Selections will range from the powerful double chorus and instrumental counterpoint of the Shutz and Bach, to the intimacy of Janequin madrigals by a group of chamber singers, to the modern complexity of Barber's Reincarnations.
This will be Miss Hiatt's second season as director of the Summer School Chorus. Under her direction the Smith College Glee Club has appeared, over the past 15 years, in Carnegie Hall, Town Hall, and Symphony Hall, and has toured England, Mexico and Italy. In Spoleto, Italy, the group was conducted by the composer Gian Carlo Menotti.
Miss Hiatt likes her groups to sing music from all periods, but thinks that contemporary music is a special test of a chorus' excellence: "This century's music is an indication of our cultural validity, and I want to deal with only that music which is vital."
