Trope (music)

A trope or tropus may be a variety of different things in medieval, 20th-, and 21st-century music.

The term trope derives from the Greek τρόπος (tropos), "a turn, a change" (Liddell and Scott 1889), related to the root of the verb τρέπειν (trepein), "to turn, to direct, to alter, to change" (Anon. 2009). The Latinised form of the word is tropus.

In music, a trope is adding another section, or trope to a plainchant or section of plainchant, thus making it appropriate to a particular occasion or festival.

From the 9th century onward, trope refers to additions of new music to pre-existing chants in use in the Western Christian Church (Planchart 2001).

Three types of addition are found in music manuscripts: (1) new melismas without text (mostly unlabelled or called "trope" in manuscripts) (2) addition of a new text to a pre-existing melisma (more often called prosula, prosa, verba or versus) (3) new verse or verses, consisting of both text and music (mostly called trope, but also laudes or versus in manuscripts) (Planchart 2001). The new verses can appear preceding or following the original material, or in between phrases.

In the Medieval era, troping was an important compositional technique where local composers could add their own voice to the body of liturgical music. These added ideas are valuable tools to examine compositional trends in the Middle Ages, and help modern scholars determine the point of origin of the pieces, as they typically mention regional historical figures (St. Saturnin of Toulouse, for example would appear in tropes composed in Southern France). Musical collections of tropes are called tropers.

Tropes were a particular feature of the music and texts of the Sarum Use (the use of Salisbury, the standard liturgical use of England until the Reformation), although they occurred widely in the Latin church. Deus creator omnium, was widely used in the Sarum Use and is in the form of a troped Kyrie.
