<p>Is he asking about the “Big Ben” chime? [Technically known as the Westminister Quarters] I thought he was referring to an an actual “hymn” (a song or ode in praise or honor of god) that was played on the “Chapel” bells. [You did mean the “chapel” bells as opposed to some miscellaneous church bells?]</p>
<p>The Westminister Quarters are actually a 20-chime sequence. Notice that at a quarter-past the hour, four tones play; at half-past, I think, 12 chimes are played; at three-quarters past the hour, 4 chimes are played and at the hour the full sequence is played [I guess the “hymn” referred to in the question.] followed by the “gong” representing the hour of the day.</p>
<p>Ahhh. . . the things you can learn on CC</p>
