“Ecco mormorare l’onde” is one of the most sung madrigals. It is famous because it is written with some characteristics of both polyphonic music and stile nuovo. The whole score enhances the style and the soloist voice. The atmosphere is set with the first sentence sung with deep ranges on a single note and then becomes livelier. The madrigal is sophisticated and alternates the polyphonic textures. There are allegro musical motives all along the song, but the melodic coherence is held. This sheet music is a piece of work!
