The article is devoted to the study of the rhythm of verse and prose by N. A. Nekrasov using quantitative methods. In this work, the poet's poems written in iambic tetrameter are considered, their correspondence to the trends in the verse of the 1840s—1880s is analyzed. Prose analysis is carried out by constructing and comparing a language probabilistic model with speech models. The results obtained on the rhythm of Nekrasov's prose turn out to be extremely similar to the data of other poets writing prose. As a result, the question of the hidden rhythmic tendency of authors who write both poetic and prose works can be raised again.
