Accentus

Accentus (or Accentus Ecclesiasticus; Ecclesiastical accent) is a style of church music that emphasizes spoken word. It is often contrasted with concentus, an alternative style that emphasizes harmony. The terms accentus and concentus were probably introduced by Andreas Ornithoparchus in his Musicae Activae Micrologus, Leipzig, 1517. "Concentus might be chief ruler over all things that are sung...and Accentus over all things that are read," according to Ornithoparchus. The style is also known as liturgical recitative, though it differs in some important ways from other types of recitative.
