, and the third of five, the last one of which is the first one of the first part; there are but two rhymes throughout. The lines of the rondel have usually eight syllables. This form was practically superseded by the rondeau (see pp. 2 and 3).
The rondeau also consists of three parts; the first has five lines, the second three, and the third five, and the first word or words of the first line, usually the first half of the line, are repeated at the end of the second and third parts; there are but two rhymes. The lines of the rondeau have also usually eight syllables (see p. 6).
The triolet consists of eight lines, usually octosyllabic. The first line is twice repeated, in the fourth and seventh places, and the second line is repeated once, making the final one. There are but two rhymes (see p. 298).
The sonnet has fourteen lines, usually Alexandrines, and is made up of two parts, one of eight lines, called the octave, and one of six, called the sestet; the rule allows but two rhymes to the octave and three others to the sestet; the arrangement of the rhymes is inflexible for the strict Petrarchan type (see below), but considerable variations from it are common. For sonnets of the strict type see pp. 257, 263, 280; for others showing variations see pp. 8, 13, 14, 199.
The rhyme arrangement of these various forms is most clearly shown by letters as follows, capital letters indicating lines that are repeated. Ballade_: eight lines, _ababbcbC_, _ababbcbC_, _ababbcbC, bcbC_; ten lines, _ababbccdcD_, _ababbccdcD_, _ababbccdcD_, _ccdcD. Rondel: ABba_, _abAB_, _abbaA_. _Rondeau: aabba_, _aab refrain, aabba refrain_. _Triolet: ABaAabAB_. _Sonnet: abba abba ccdede.
