The short title of a printed collection of ninety-six songs published by Petrucci in 1501 -- Harmonice musices Odhecaton A. The volume was the earliest-ever printed polyphonic music; it is very important for its representation of secular polyphony in the period ca. 1470 - 1500.

Similar collections called Canti B and Canti C followed in 1502-3.
