Westminster Quarters

Westminster-chimes.mid: a midi file playing Westminster Quarters striking six o'clock

The Westminster Quarters is the most common name for a melody used by a set of clock bells to chime on 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, or the Cambridge Chimes from its place of origin, the church of St Mary the Great, Cambridge.

Description

The melody consists of five different permutations of four pitches in the key of E major. The pitches are B3, E4, F4 and G4.

The permutations 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 dotted minim. These permutations are always played in order, and each permutation is used twice every hour. Different quantities of permutations are played at each quarter-hour: one set at the first quarter, two sets at the half, and so forth, as follows:

First quarter: (1)
Half-hour: (2) (3)
Third quarter: (4) (5) (1)
Full hour: (2) (3) (4) (5)
Big Ben

The full hour chime is followed by one strike for the number of the hour by Big Ben (e3) (one strike for one o'clock, two strikes for two o'clock, etc.).

In other words, a cycle of five permutations, (1), (2), (3), (4), (5), is repeated twice during the course of an hour. For a clock chiming mechanism, this has the advantage that the mechanism that trips the hammers need only store five sequences (1, 2, 3, 4, 5) instead of ten. The mechanism then plays two complete sets of five sequences for each complete hour. In musical terms, the first and third quarters finish on the dominant (B), whilst the second and fourth quarters (the half and full hours) finish on the tonic (E). This produces the very satisfying musical effect that has contributed so much to the popularity of the chimes.

History

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 measures of "I know that my Redeemer liveth" from Handel's Messiah.[1] This is why the chime is also played by the bells of the so called 'Red Tower' in Halle, the native town of Handel. 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 (1715-99), who was the Professor of Music from 1755, or his brilliant undergraduate pupil, William Crotch (1775-1847).

In the mid-19th century the chime was adopted by the clock tower at the Palace of Westminster (where Big Ben hangs), whence its fame spread. It is now possibly the most commonly used chime for striking clocks.

According to the church records of Trinity Episcopal Church (Williamsport, Pennsylvania), 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.

Other uses

The chime is also used in some doorbells and school bells. Most Japanese and Taiwanese schools play the chimes to signal the end and beginning of periods.

Words

Customary lyrics for the tune are:

O Lord our God
Be Thou our guide
That by thy help
No foot may slide.

An alternative lyric changes the third line:

O Lord our God
Be Thou our guide
So by Thy power
No foot shall slide.

A variation on this, to the same tune, is sung at the end of a Brownie meeting in the UK and Canada:

Oh Lord our God
Thy children call
Grant us Thy peace
And bless us all.

A lyric inscribed in the Big Ben clock room is:

All through this hour
Lord, be my guide
And by Thy power
No foot shall slide.
