The words of the Lutheran chorales were often Latin plainsong hymn texts translated into the vernacular. The melodies were often borrowed from secular song and therefore displayed great melodic and structural simplicity. In modern times the chorale is considered to be a musical setting, usually polyphonic (multivoiced), of a traditional religious text
