Westminster Quarters


The Westminster Quarters is the name for a melody used by a set of striking clock bells to mark each quarter-hour. The number of chime sets matches the number of quarter hours that have passed. It is also known as the Westminster Chimes, from its use at the Palace of Westminster, or the Cambridge Quarters from its place of origin, the church of St Mary the Great, Cambridge.

Description

The melody consists of four different permutations of four pitches in the key of E major plus one arrangement omitting B3 and repeating E4. The pitches are B3, E4, F4 and G4.
The notes used are:
  1. G4, F4, E4, B3
  2. E4, G4, F4, B3
  3. E4, F4, G4, E4
  4. G4, E4, F4, B3
  5. B3, F4, G4, E4
played as three crotchets and a minim. These are always played in the order 1, 2, 3, 4, 5, and each set is used twice every hour. Set 1 is played at the first quarter, sets 2 and 3 at the half, sets 4, 5 and 1 at the third quarter, and sets 2, 3, 4 and 5 at the hour, as follows. Note that these sounds have been recreated as electronic, midi files and do not necessarily represent the actual sounds of the bells:

History

It was written in 1793 for a new clock in St Mary the Great, the University Church in Cambridge. There is some doubt over exactly who composed it: Revd Dr Joseph Jowett, Regius Professor of Civil Law, was given the job, but he was probably assisted by either Dr John Randall, who was the Professor of Music from 1755, or his brilliant undergraduate pupil, William Crotch. This chime is traditionally, though without substantiation, believed to be a set of variations on the four notes that make up the fifth and sixth bars of "I know that my Redeemer liveth" from Handel's Messiah. This is why the chime is also played by the bells of the so-called 'Red Tower' in Halle, the native town of Handel.
In 1851, the chime was adopted by Edmund Beckett Denison for the new clock at the Palace of Westminster, where Big Ben hangs. From there its fame spread. It is now one of the most commonly used chimes for striking clocks.
According to the church records of Trinity Episcopal Church, this chime sequence was incorporated into a tower clock mechanism by the E. Howard & Co., Boston, MA. The clock and chime in Trinity's steeple base was dedicated in December 1875. It holds the distinction of being the first tower clock in the United States to sound the Cambridge Quarters.
