Features of the Functionality of the Harmonic Progression II–V as a Main Element of the Musical Jazz Vocabulary

Summary/Abstract: The purpose of the article is identifying the harmonic and functional characteristics of the main elements of jazz harmony, namely the harmonic progression II–V. To achieve the goal of the article, the following research methods were used: comparative (for a comparative analysis of the harmonious functionality of academic and jazz music); method of musicological analysis (for musicological analysis of jazz standards); method of stylistic analysis (to identify the stylistic characteristics of certain styles of jazz music); method of generalization (to summarize the study). Scientific novelty. In the presented scientific work, for the first time in Ukrainian musicology, an attempt was made to theoretically comprehend the functional connections within the framework of the harmony of jazz music. Conclusions. Harmonic formula II–V is the single functional link of jazz harmony, the main characteristic of which is the dominant functionality. Since the phenomenon of dominance is the main impetus for the implementation of musical development, the harmonic progression II–V is not only the main harmonic formula, but also a leading element of the harmonious development of jazz music. This statement is an impulse to rethink harmonious functionality in the context of jazz music and, in particular, to understand the function of harmonic progression II–V, which will lead to a fuller and deeper understanding of jazz music by its performers and, consequently, listeners.
