Quelle est cette odeur agréable

"Quelle est cette odeur agréable?" (in English, "Whence is that goodly fragrance flowing?") is a 17th-century traditional French Christmas carol about the Nativity.

The carol is sometimes set to music written by John Gay for The Beggar's Opera in 1728. Another version for four-part choir and baritone solo was arranged by David Willcocks.

Frank Houghton wrote the hymn "Thou who wast rich beyond all splendour" to the melody of this French carol.
