My business is repairing or setting up grandfather clocks.
I tune the chimes,listen carefully for bad notes and making the corrections as needed.
All grandfather clocks play Westminster chimes,some play 3 chimes.
The are reasons for all the chimes,some are religious,some are from church bells and some are taken from children's nursery rimes.
Westminster chimes are the most popular,made famous by Big Ben in London.
However the chimes were first set into the tower at University Church, St. Mary's the Great, in Cambridge, England.
The actual words are:
"Lord, through this hour,
Be Thou our guide
So,by thy power
No foot shall slide"
The music was Handels symphony,"I Know That My Redeemer Liveth'.The words and music were arranged by William Crotch in 1793.
Even for the non religious people who have clocks in their homes,they are hearing a prayer every quarter hour.
I like that and find it fun to explain it to people.
