The classical alexandrin's two hemistiches of six syllables each, separated by the caesura, create the defining rhythmic structure of French classical poetry: "Dans l'Orient désert // quel devint mon ennui" (Racine) demonstrates the perfect 6+6 balance; Hugo's trimètre breaks the alexandrin into three equal hemistiches of four syllables: "Je veux, // j'aime, // je souffre" creates a three-beat rhythm that distributes the line's emotional weight across three equal units rather than two; The interplay between the two hemistiches of an alexandrin can create agreement, where both develop the same idea, or tension, where they oppose each other: "Il vivait pour la gloire // et mourut pour l'amour" uses antithesis between the hemistiches to crystallize a character's essential
contradiction; A student analyzing French poetry should mark the hemistich divisions in every alexandrin they
study, noting whether the hemistiches are syntactically parallel, antithetical, or asymmetrical, and considering how the relationship between them contributes to the line's meaning; The feminine hemistiche, ending on a mute e that adds
a shadow syllable beyond the counted six, creates a different rhythmic feel from the masculine hemistiche ending on a stressed syllable, and skilled poets alternate
these endings with expressive intention; Racine's mastery of the hemistiche is visible in his ability to make the pause between the two halves of a line carry enormous dramatic weight: the silence at the caesura can express hesitation,
horror, or revelation more powerfully than any additional word.
