If you have a clock in your town or home that chimes the quarter hour, you can easily say a prayer on the hour that can be sung to the chimes.  Here are two different prayers you can use.

From Mary Lou Carney, Senior Editor, Guideposts

Mary Lou had a clock in her hallway that chimes the full 16 notes of the Westminster chimes on the hour.  This is the four part prayer that she learned as a child listening to the clock.

Lord through this hour,
Be thou our guide.
Kept by thy power,
No foot shall slide.

 

From my own experience.

Here is a prayer that I learned that can be sung to Westminster chimes.  This one is more of a table blessing: 

 

Hark to the chimes,

Come bow your head

We thank thee Lord

For this good bread
