In musical settings of the Credo, as in the Gloria, the first line is intoned by the celebrant alone ("Credo in unum Deum"), or by a soloist, while the choir or congregation joins in with the second line. This tradition continued through the Middle Ages and Renaissance, and is even followed in more recent settings. In Stravinsky's Mass, for example, a soloist intones the first line, which is from the plainchant Credo I. In Mass settings of the Baroque, Classical and Romantic period the Credo line is usually set for whole choir, such as in the "Symbolum Nicenum" (Nicene Creed) of Bach's Mass in B minor, where the composer uses plainchant as the theme for a fugue, in the later Masses of Haydn, and the "Missa Solemnis" of Beethoven.
