Luca Marenzio
Marenzio published at least fifteen collections of music, mostly madrigals but also canzonette and villanelle.  These were similar to madrigals but very light in character.  Some of his later works are very chromatic: they use harmony that was unusual for the time.  He often makes the music fit the meaning of the words.  This is called word-painting.  For example: the phrase "sinking in the sea" is sung to notes which go lower and lower.
