Abstract: The 19th century gave the world many talented opera performers, each of whom had his own artistic charisma and unique style of vocal performance. One of these singers was the bass-baritone Antonio Tamburini, a master of interpretation of the roles of Gioacchino Rossini, Vincenzo Bellini, Gaetano Donizetti, Saverio Mercadante, Giovanni Paccini, Carlo Coccia and Wolfgang Amadeus Mozart. The subject of the research is the work of the early 19th century operatic baritone Antonio Tamburini. The object of the study is the opera parts performed by Tamburini over the years of work in theaters. The relevance of the study is due to the role of Antonio Tamburini in the formation and development of the baritone art at the beginning of the 19th century, as well as the lack of knowledge of the processes that took place in opera art in the era of early romanticism. This period is covered in the musicological works of O.V. Zhestkovoy, L.A. Sadykova, I.P. Drach, G. Potter, A. Jacobshagen, J. Stark, A.E. Hoffmann, S.V. Reshetnikova, however, the mentioned works are mainly devoted to the study of the operatic performance of tenors and sopranos. The period of the birth of baritone performance was not considered in the above works, and the work of Antonio Tamburini remained unexplored, which indicates the undoubted novelty of the work. The article focuses on primary sources: the singer's creative biography, described by the 19th century music critic Castile-Blaz, contemporaries' reviews of Antonio Tamburini's stage performances. The work is dominated by historical and theoretical research methods. The main conclusion of the work is to identify the main aspects of the performing style of Antonio Tamburini, revealing the secret of the uniqueness of his art.
