"Ding Dong Merrily on High" is a Christmas carol. The tune first appeared as a secular dance tune known as "le branle de l'Official" in Orchésographie, a dance book written by Jehan Tabourot (1519–1593). The lyrics are from [bad word] George Ratcliffe Woodward (1848–1934), and it was first published in 1924 in his The Cambridge Carol-Book: Being Fifty-two Songs for Christmas, Easter, And Other Seasons. Woodward took an interest in church bell ringing, which no doubt aided him in writing it. Woodward was the author of several carol books, including Songs of Syon and The Cowley Carol Book. The macaronic style is characteristic of Woodward’s delight in archaic poetry. Charles Wood harmonised the tune when it was published with Woodward's text in The Cambridge Carol Book. More recently, Sir David Willcocks made an arrangement for the second book of Carols for Choirs.
The song is particularly noted[1][2] for the Latin refrain:
Gloria, Hosanna in excelsis!
[Glory! Hosanna in the highest!]
where the sung vowel sound "o" of "Gloria" is fluidly sustained through a lengthy rising and falling melismatic melodic sequence.

Ding dong! merrily on high
In heav'n the bells are ringing:
Ding dong! verily the sky
Is riv'n with Angel singing.
REFRAIN
Glo-o-o-o-o-o-ria,
Hosanna in excelsis!
Glo-o-o-o-o-o-ria
Hosanna in excelsis!
E'en so here below, below,
Let steeple bells be swungen,
And "Io, io, io!"
By priest and people sungen.
REFRAIN
Pray you, dutifully prime
Your matin chime, ye ringers;
May you beautifully rime
Your evetime song, ye singers.
