This type of poem has a "mote"—the beginning of the poem, which functions, when in music, as a refrain—followed by one or more intervening stanzas—the "volta", "copla" or "glosa"—each one with 7 lines. The difference between the "vilancete" and the "cantiga" depends on the number of lines in the mote: if there are 2 or 3 it is a "vilancete", if there are 4 or more it is a "cantiga". Each line of a vilancete is usually divided in five or seven metric syllables ("old measure"). When the last line of the mote is repeated at the end of each stanza, the vilancete is "perfect".
