Tintinnabulation was one of my fifth grade spelling words.
In about the 5th grade I was in a spoken-word chorus that performed the first stanza of Poe's THE BELLS for our school Christmas pageant and we had to learn to pronounce "tintinnabulation:"
Hear the sledges with the bells -
Silver bells!
What a world of merriment their melody foretells!
How they tinkle, tinkle, tinkle,
In the icy air of night!
While the stars that oversprinkle
All the heavens seem to twinkle
With a crystalline delight;
Keeping time, time, time,
In a sort of Runic rhyme,
To the tintinnabulation that so musically wells
From the bells, bells, bells, bells,
Bells, bells, bells -
From the jingling and the tinkling of the bells.
