Ding Dong Merrily on High

Though the carol “Ding Dong Merrily on High” was published in 1924 the tune first appeared in a dance book written by Jehan Tabourot (1519 - 1593). It’s macaronic in style (Latin and English lyrics) and also contains a lengthy passing and falling mellismatic melodic sequence on the “o” of “Gloria!”
Ding Dong, merrily on high!
In heav’n the bells are ringing;
Ding Dong, verily the sky
Is riv’n with angel singing.
Gloria, hosannah in excelsis!
Gloria, hosannah in excelsis!
E'en so here below,
Let steeple bells be swungen,
And io, io, io,
By priest and people sungen.
Gloria, hosannah in excelsis!
Gloria, hosannah in excelsis!
Pray ye dutifully prime
Your matin chime, ye ringers;
May ye beautifully rhyme
Your evetime song, ye singers.
Gloria, hosannah in excelsis!
Gloria, hosannah in excelsis!
