freer section where the subject is not heard in its entirety.
composition for 2, 3, 4, or 5 parts played or sung by voices or instruments, which begins with a presentation of a subject in imitation in each part (exposition), continues with modulating passages of free counterpoint (episodes) and further appearances of the subject, and ends with a strong affirmation of the tonic key.

showy passage for soloist alone toward the end of a movement.
multimovement sacred work including arias, ariosos, and recitatives, performed by vocal soloists, a chorus, and a small accompanying orchestra.
spiritual melody or religious song of the Lutheran Church--what other dominations would simply call a hymn.
