The beauty of unison female voices is heard in the first stanza of this engaging melody by Herb Frombach. Alluding to ""Angels We Have Heard on High"" in the accompaniment, a fragment of the hymn tune is used for modulation into the second stanza. Solid four-part singing in the next section is followed by a soft restatement of the opening phrase, ""Once upon a midnight."" A beautiful and contemplativepiece, ideal for Christmas or Christmastide services.
