In music, a dictum (Latin 'something that has been said'; plural dicta) is a type of libretto for a church cantata consisting of quotes from sacred scripture.
When Erdmann Neumeister introduced the cantata concept for sacred music in early 18th-century Protestant Germany, his librettos originally had only two types of movements: recitatives and arias. The text of these movements was the poetic (i.e., in verse) elaboration of some religious thought. In Neumeister's original concept both of these types of movements were to be sung by vocal soloists. Soon thereafter, for instance in a set of cantata librettos published in Meiningen in 1704, two other types of movements, both deriving from earlier genres such as Chorale concerto and Geistliches Konzert, were combined in the cantata librettos: chorales and dicta. The chorale movements typically quoted from Lutheran hymns. For these movements the composer was expected to base his setting on the tune of the hymn. The dicta were prose quotes from sacred scripture, i.e., for German church cantatas and motets of the Reformation era, quotes from the Luther Bible. In this context a dictum can also be referred to with the German word German: Spruch . Libretto authors such as Neumeister and Benjamin Schmolck began to include dicta and chorales in their later cantata cycles.
For the musical setting of dicta there was no fixed format:
