Background. The article provides an analysis of L. Beethoven’s piano quartets through the prism of the ensemble writing and composition experience by W. A. Mozart. The disclosure of the successive ties between the two great Viennese classics in the field of chamber instrumental music contributes to the scientific understanding of the history of this genre, which is not sufficiently covered in musicology. The analysis revealed that the four piano quartets of L. Beethoven are focused on Mozart’s prototypes, or rather, on sonatas for violin and piano. It was found that the formative principles of Beethoven’s piano quartets grow from the above-mentioned compositions by W. A. Mozart, but the content and the ensemble-dramatic solution reflect the independence and originality of the young composer’s thinking, revealing the sprouts of a future mature style. The purpose of this article is to disclose the ways of rethinking the prototypes of Mozart in the piano quartets of L. Beethoven. The piano quartets of the latter serve as the musical material of the article: No. 1 Es-dur, No. 2 D-dur, No. 3 C-dur WoO 36, and No. 4 Es-dur op. 16. Results. L. Beethoven changes the algorithm of ensemble events contained in Mozart’s opuses, where the theme is presented in turn by piano, violin, followed by the conversation of the two. The composer immediately includes all members of the quartet in the presentation of the leading material, which specifies this genre, revealing its “intermediateness” between the intimacy of the trio and the “representativeness” of the concerto. Since the genetic origins of the genre of the piano quartet are the trio sonata, the string quartet and the clavier concerto with the accompaniment of a string ensemble, these genres influenced the type of Beethoven’s piano quartets. Thus, Beethoven’s Bonn quartets resemble in their writing a string quartet; and the piano quartet Es-dur op. 16 resembles a clavier concerto with orchestra. These compositions are related to the first of the above mentioned prototypes by the consistent application of the trio principle, which is expressed in various combinations of ensemble voices. In the timbre refraction, the trio-principle underlies the pairing of stringed instruments, where the bowed instruments form a strictly homophonic vertical with the traditional functional relationship according to the “upper voice ‒ bass ‒ middle” model. Another dimension of the trio principle arises when one of the string parts of the piano is displaced, as a result of which a multi-timbre sound field is formed. There is an obvious desire of the composer for the equality of four voices in the piano quartet. At the same time, the timbre uniqueness of the piano and the virtuosity of its part make it possible to recognize in it the leader of the ensemble union. Conclusion. The leading role of the piano in L. Beethoven’s piano quartets brings this genre closer to a piano concerto. At the same time, the piano has a variety of role functions: it can act as an equal partner, being one of the voices of the quartet score; as a concert instrument demonstrating its virtuoso capabilities; as a leader of an ensemble, a kind of conductor, giving impetus to performance, initiative in ensemble play. Similar functions can be observed in W. A. Mozart’s sonatas for violin and piano, which L. Beethoven was guided by.
