The last generation of composers of the era included Niccolò da Perugia, Bartolino da Padova, Andrea da Firenze, Paolo da Firenze, Matteo da Perugia, and Johannes Ciconia, the first member of the group who was not a native Italian. Though the principal form remained the ballata, a resurgence of the madrigal shows an interest in earlier music. This interest is accompanied by renewed interest in purely Italian notation. In many works by the newest generation the ornamentation of the parts is considerably less than in the music of the preceding group of composers, while other compositions are as ornamented as any in the earlier Trecento. Text-painting is evident in some of their music: for example, some of their programmatic compositions include frank imitations of bird calls or various dramatic effects.
