The motet is an unaccompanied sacred musical composition for chorus, of a Latin text, not specifically connected to the liturgy of a given day, and therefore suitable for use in any service.
Ave Maria is a well known example.
This one was composed by Tomás Luis de Victoria
A chorale is a melody to which a hymn is sung by a congregation in a German Protestant Church service.
They are written in German and are usually sung in four-voices harmony, in which the sopranos (and the congregation) sing the melody.
Martin Luther composed some chorales himself, such as A Mighty Fortress is our God (Ein feste Burg ist unser Gott) He wrote the words and composed the melody sometime between 1527 and 1529.
