“Angels We Have Heard on High” is generally sung to the hymn tune “Gloria,” a traditional French carol as arranged by Edward Shippen Barnes. Its most memorable feature is its chorus, Gloria in Excelsis Deo, where the “o” of “Gloria” is fluidly sustained through 16 notes of a rising and falling melodic sequence.
In England, the words of James Montgomery’s “Angels from the Realms of Glory” are usually sung to this tune, with the “Gloria in Excelsis Deo” refrain text replacing Montgomery’s. It is from this usage that the tune sometimes is known as “Iris,” the name of Montgomery’s newspaper.
