 Her published compositions span a period of 60 years, beginning with the dialogues of 1640 and concluding with the "Motetti a voce sola" of 1700.Leonarda is credited with producing nearly two hundred compositions during that period, though her only works appearing before 1670 were the dialogues printed by Gasparo Casati.It appears that she was over the age of 50 before she started composing regularly, and it was at that time that she began publishing the works that we know her for today.
