The Cornell Chimes

The tower will be under construction and will be receiving some tender, loving, and care! However, do not worry too much, as the chimes will still be ringing throughout campus (on a modified and limited schedule). The tower will be an active construction zone, which means it will be CLOSED to the Cornell community and the public. Please visit the library space projects website for information on the construction project. We will plan a re-opening celebration once construction ends and the tower is accessible!

The bells of Cornell referred to as the Cornell Chimes, are the heartbeat of campus life, marking the hours and chiming daily concerts. The original set of nine bells, a gift of Jennie McGraw, first rang out at the university's opening ceremonies on October 7, 1868. Over time the chime has been recast and expanded to 21 bells. Three concerts are performed each day while classes are in session.

Chimesmasters

The bells are played by student and alumni chimesmasters. The small staff performs daily concerts during the school year and a reduced schedule during the summer and semester breaks, as well as a variety of specialty concerts. Each spring, a rigorous ten-week competition is held for anyone interested in becoming a chimesmaster. There is no electronic assistance to the playing mechanism - all the work is done by the player. In the 1940s, a chimesmaster received physical education credit for his efforts!

Music of the Bells

Virtually every kind of music is played on the bells, from Baroque to Beatles, Chopin to Coldplay, selected from a collection of more than 3000 pieces arranged for the Cornell Chimes by current and former chimesmasters. There are even duets. Because of the direct link between the playing stand and the bell clapper, it is possible to vary the dynamics of the music.

Signature Music

The chimesmasters honor a “3-week rule” where a piece of music cannot be repeated within three weeks unless it is a visitor request or one of the signature musical pieces. The "Cornell Changes," known affectionately as the "Jennie McGraw Rag," in honor of the donor of the original bells, begins every morning concert. Aspiring chimesmasters must memorize the “Rag’s” 549 notes. Also played daily are the "Cornell Alma Mater" at the end of the midday concert and the "Cornell Evening Song" at the end of the evening concert. Listen to the bells.

McGraw Tower

Tower History

The bells were originally played on a ground-level playing stand before moving to McGraw Hall in 1873. The small tower in McGraw Hall was never intended for the bells, and accounts from that time claim the building shook each time the bells were rung!

In 1891 the university finished the construction of Uris Library and Library Tower. At that time, the bells were moved to their permanent home (later renamed McGraw Tower). Local architect William Henry Miller designed the 173-foot tower and adjacent library.

The seven rooms in the tower were initially used to store the library's stacks. They now are home to the chimes office, museum, practice room, and the 1875 Seth Thomas clock with a 14-foot pendulum. The clockworks and pendulum can still be seen in the tower, but a computer now operates the clock.

McGraw Tower gained national attention when a pumpkin mysteriously appeared on the top of the tower in October 1997.

Clock Face Lighting

The tower, a university symbol, is known to take on different appearances during the school year thanks to a LED lighting system. Every Halloween, the glowing clock faces resemble jack-o-lanterns. In March, the clock faces take on a greenish hue in anticipation of the Dragon. Visit our Policies page for more information about tower lighting.

Visiting the Tower

Starting on July 3rd, 2023: The tower will be under construction and will be receiving some tender, loving, and care! However, do not worry too much, as the chimes will still be ringing throughout campus (on a modified and limited schedule). The tower will be an active construction zone, which means it will be closed to the Cornell community and the public. Please visit the library space projects website for information on the construction project. We will plan a re-opening celebration once construction ends and the tower is accessible!
