The Harmonice Musices Odhecaton (One Hundred Songs of Harmonic Music,[1] also known simply as the Odhecaton) is an anthology of polyphonic secular songs published by Ottaviano Petrucci in 1501 in Venice. It is the first book of polyphonic music ever to be printed using movable type. (Printing plainchant with movable type had been possible since the 1470s.)[2] The Odhecaton was hugely influential both in publishing in general and in dissemination of the Franco-Flemish musical style.
