The serena (evening song) is a minor Old Occitan lyric genre.
In the serena, the lover complains of the long wait for evening to arrive so he can consummate his love.
[1][2][3] The genre was invented late in the history of the Occitan lyric by the troubadour Guiraut Riquier in his song Ad un fin aman fon datz (A true lover once awaited), which he claimed to have completed in the year 1263, when he was living in Narbonne.
[4] The refrain of Guiraut's serena goes: e dizia sospiran: —Jorns, ben creyssetz a mon dan, e·l sers auci·m e sos loncx espers.
[1] And with a sigh he said, "Day, you grow long to my harm, And this evening Is killing me with waiting.
