Charles A. Baird Missouri from 1921 until at least 1937, also acting as the President of the Board for several years. In his later years, Baird became a benefactor of the University of Michigan. His most prominent gift was the Charles Baird Carillon, a carillon consisting of 53 bells that was the third heaviest in the world in 1936. The carillon was purchased with a $70,000 gift from Baird. When Baird first offered the carillon to the university, the Burton Memorial Tower had not been built. The school initially set aside $35,000 to house the carillon in the tower of the Michigan Union.
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.
