The objective of this dissertation, inspired by performance experience, was to establish the similarities in the use of recitative style in the music of Claudio Monteverdi and Giuseppe Verdi. To achieve this objective, their use of recitative style was examined through comparative analysis of four scenes from their operas: “Arianna's Lament” from L'Arianna and “Disprezzata regina” from L'incoronazione di Poppea by Monteverdi, and “Condotta ell'era in ceppi” from Il trovatore and “Judgment Scene” from Aida by Verdi. The examination of the similarities included a discussion of the following: (a) the historical influences and cultural backgrounds of the composers; (b) general similarities in their compositional approaches to recitative style; (c) comparable characteristics of the dramatic recitative style in the early Baroque monody and in Verdi's operas; (d) similarities in musical characterization and expression of affective and emotional content through stylistic musical devices; (e) similarities in the composers' approaches to vocal and acting issues with special emphasis on the problems of diction; and (f) some related performance-practice issues. A discussion of the poetic lament and the influence of its form and content on musical setting was also a part of this research. The comparative research revealed numerous similarities in the historical circumstances influencing Monteverdi's and Verdi's choice of musical styles; their motivation; formal and stylistic characteristics of their dramatic recitative scenes; their choice of libretto; their use of the elements of lament; their musical treatment of emotional content of the text; and their prerogatives in vocal and acting issues. Numerous similar characteristics were also established regarding vibrato, tempo, rhythm, and ornamentation in the performance practice of the early Baroque recitative soliloquy and Verdi's dramatic recitative scenes. The similarities of the four scenes' functions, topics, form, and characterization through devices of musical style indicated a fundamental continuity in the development of Italian opera from its inception to the end of the nineteenth century.
