A Dictionary of Music and Musicians/None

NONE (Lat. Officium (vel Oratio) ad Horam Nonam, Ad Nonam). The last of the 'Lesser Hours,' in the Roman Breviary.

The Office consists of the Versicle, and Response, 'Deus in adjutorium'; a Hymn—'Rerum Deus tenax vigor'—which never changes; the last forty-eight verses of the Psalm, 'Beati immaculati,' sung in three divisions, but, under a single Antiphon; the Capitulum, and Responsorium for the Season; and the Prayer, or Collect, for the Day. The Plain Chaunt Music for None will be found in the 'Antiphonarium Romanum,' and the 'Directorium Chori.'
