Music for these texts was composed usually in two, sometimes in three voice-parts, in a form that closely follows that of the poetry, the same music being provided for the strophes and different music for the ritornello, so that the two-stanza (8-line) madrigal has the form a a b, and the three-stanza (11-line) madrigal has the form a a a b. The normal form, a a b, is similar to, but probably not derived from, the French ballade.
Madrigals were composed chiefly by the members of the early Italian school, whereas in the second half of the 14th century the madrigal was largely abandoned in favor of the ballata.
