If the lower part was added extempore, it was called Descant, but if written down as here, it was called Prick-song, because 'pricked' down. The Plain-song is perhaps more often found in a lower part, the Descant being higher. From the position of the added part, the above example is called 'bass' descant.

The 'Ground' itself is in large notes, the necessary chords (which were never written down) are indicated in small notes. This the Organist or Harpsichordist plays again and again, as often as necessary.
