Note 84 — Chapter VIII · THE RISE OF THE NETHERLAND SCHOOLS

Strict or plain counterpoint is divided into several species: (1) note against note, there being one note in the accompanying melody or melodies to one note of the cantus firmus; (2) two notes against one; (3) three, four, or more notes against one; (4) syncopated; (5) florid or figured, in which the added parts are free. Counterpoint is single, or simple, when the added part is uniformly above or below the cantus; double when the added part is so constructed as to be usable either above or below the cantus by a uniform transposition of an octave, a tenth, or some other interval; and triple, or quadruple, when three or four melodies are so fitted as to be mutually interchangeable with one another by transposition.
