Sólo cànta mi lìra.
In older Spanish, the alexandrine often consisted of two seven-syllabled iambic verses or half-lines, separated by the cæsura. There might be one or two unaccented syllables after the stressed sixth, and the unaccented syllables did not coalesce with the second half-line, since hiatus, rather than synalœpha, prevailed in Old Spanish; e.g., Berceo:
En esta romería | habemos un buen prado.
El fruto de los árbores | era dulze sabrìdo.
Some modern poets have imitated this alexandrine, avoiding the hiatus, however.
The five-syllabled (pentasyllabic) iambic verse has a xxxvi necessary stress on the fourth syllable. In this line the iambics easily yield to dactyls; e.g., Moratín:
El que inocente
La vìda pàsa
No necesìta
Morìsca lànza,
