Exceptions naturally occur where the set text differs from the published text of the libretto.
E via se li reca al diletto, suo nido, negli alti reami. Where the scores include additional or modified text I have been guided in part by meter and rhyme, in part by following the musical line, and in part by a desire to retain repeated words and interjections in the original line so as not to break up the sense. Occasionally re-lineation is unavoidable, for example, No. The most important exception to the preservation of poetic lineation is for stage instructions, which are inserted in the text as close as practicable to the point at which they occur in the score, and which are generally printed on separate lines, except for very short instructions. Also, extra line breaks are occasionally inserted where required for the sake of denoting the commencement or termination of sections of parallel text sung in ensemble.
