In 15th Century Italian Dance the ballo (pl. balli) is a dance style that existed alongside the bassadanza. It is distinguished by its nore lively nature and mix of misure. For instance Rostiboli Gioioso moves from bassadanza misura, to saltarello and then to piva.
In the middle of the 15th century bassadanza was the more common style, but by the last decades the balli seem to have taken over, and their descendants were well and truly dominant in 16th Century Italian Dance.
