Cook Carillon Tower around 3,000 pounds and the smallest at just 14 pounds with sizes ranging from 51.7 to 7.5 inches. The tower itself is made of brick and stone. The carillon chimes at every quarter-hour throughout the day on a set computerized play system playing the Whittington chimes. The carillon also automatically plays the university's alma mater, "Hail to Thee, Grand Valley" after the noon chimes.

A♭ (musical note) A♭ (musical note) A (A-flat; also called la bémol) is the ninth semitone of the solfège. It lies a diatonic semitone above G and a chromatic semitone below A, thus being enharmonic to G, although in some musical tunings, A will have a different sounding pitch than G. When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of the A above middle C (or A) is approximately 415.305 Hz. See pitch (music) for a discussion of historical variations in frequency. A/G is the only note to have only one other enharmonic.
