Mutos consist of paired verses, usually one slightly longer than the other (for example 3 + 4 lines). The first is known as the isterrina and the second as the torrada, with the torrada repeating part of the isterrina.[2]
The plural of mutu in Sardinian is mutos. However, they are variously also known as muttu, mutettu, repentina or ottada. The term mut(t)u prevails in the northern part of the island and is attested since the 8th century.[3]
