from Wikipedia, the free encyclopedia

Quintorganum is a very early form of polyphony in Gregorian music from around the 9th century AD. The main melody was sung by the so-called principal voice. The same melody was sung exactly a fifth lower by another voice ( vox organalis ).

In contrast to the fourth organ , the distance between fifths was strictly adhered to in this form of music.
