Act IV, are in _romance heroico_, with assonance in _á-a_.

The _redondilla_ consists of four octosyllabic lines, with consonantal rime, usually arranged thus: _abba_. In Act I, for example, lines 111-458 consist of 87 _redondillas_.

The _quintilla_ consists of five octosyllabic lines, with two consonantal rimes, arranged so that no more than two may come together: _ababa, abbab, abaab_, etc. In Act III lines 62-226 consist of 33 _quintillas_. The last one has a very unusual combination of rimes: _abbba_.

The _décima_ consists of ten octosyllabic lines, with four consonantal rimes usually arranged as in lines 761-770, or 771-780, Act II: _abbaaccddc_. The _décima_ is not properly considered as two _quintillas_, since there should be a pause at the end of the fourth line of a _décima_.

The _copla_ (stanza) _de arte mayor_ contains eight lines with three consonantal rimes arranged thus: _abbaacca_. Each line is divided into two hemistitches, with rhythmic stress on the fifth syllable of each hemistich. The sixth syllable of either hemistich or of both may be lacking, so that there may be a total of 10, 11, or 12 syllables in a line. Lines 179-282, Act II, are made up of thirteen _coplas de arte mayor_. Most of the lines have 11 or 12 syllables; note that verses 187, 200, 215, etc., have only ten each.

The _silva_ is usually composed of eleven-syllabled lines, intermingled with lines of seven syllables. There is consonantal rime, but without regularity; and many lines are left unrimed. An example of the _silva_ may be found in lines 309-437, Act III.
