Madrigal

Explanation:

During the renaissance, a madrigal was a popular European musical piece constructed with polyphonic voices (usually four or six voices), every tune was different in each line, and was sometimes accompanied by instruments.  

One of the main themes found in madrigals were short reflections on love, but themes of death or somber ones were also found.
