This article examines the genre-strophic potential of G.V. Golohvastov’s septets – an emigrant poet, who went to New York due to historical cataclysms in the beginning of XX century. His creative art gives live to researches of formal and substantive septet aspects, possible deviations and poetic experiments, intended to vary the canon and to challenge it. The genesis and a genre form develpoment are visible in this article: from single poetic experiments to genre-strophic unity (twin kernel, suite, septet sequience).
