A mutu is a type of improvised sung poetry found in Sardinia. These are traditionally sung mostly by women in response to the male. This type of improvisation called Battorinas (in English: quatrains).
Mutus consist of paired verses (in sardinian: duina), usually one slightly longer than the other (for example 3 + 4 lines). The first is known as the isterrida (opening) and the second as the torrada (response), with the torrada repeating at the argument of the isterrida. The mutos are sung during the gara (competition) of the cantu a chiterra.
