A carillon consists of 23 or more cast bronze bells connected with mechanical wires to a keyboard and a pedalboard. The keyboard is similar to that of a piano; it is split into two rows of spindle-like wooden keys that are struck by half-closed fists. The pedalboard, similar to that of an organ, controls the two lowest octaves. Repertoire ranges from original compositions to arrangements of classical music, 赞美诗, and popular melodies.
The McDonogh 钟琴, one of approximately 180 in North America and only three in Maryland, includes 48 bells weighing a total of nearly 10 tons. The smallest is 24 pounds and has a diameter of 7 ½ inches; the largest weighs more than 1.6 tons and has a diameter of 53 inches. The bells were cast and tuned in The Netherlands by the Petit and Fritsen Foundry, which dates back to 1660. Additionally, there is a practice keyboard in the bell tower that is attached to a set of tuned bars, similar to a xylophone.
Throughout the year, the carillon chimes the Westminster Quarters and Hours. When school or camp is in session, 23 bells are programmed to play a hymn or familiar tune every weekday in the morning and again in the afternoon.
Buck Lyon-Vaiden is McDonogh's resident carillonneur. He learned to play at the University of the South in Sewanee, Tennessee. Lyon-Vaiden plays for many events during the school year, including Dedication Day, the 校友 Memorial Service, Head of School Day, and Commencement. By request, he will play for weddings and other ceremonies on campus.
During the summer of 2024, McDonogh will host the 46th Annual Summer 钟琴 Concert Series. The free concerts will be held rain or shine. Guests are invited to picnic on the grounds surrounding Tagart Memorial Chapel or enjoy the recitals from inside. Children are welcome to use the Lower School playground behind Elderkin Hall. Tours of the tower will be given after each concert.
The 2024 schedule and performers will be announced in the spring.
