As every scientific discipline, musicology has some peculiarities. One of them is diversity of musicological domain. Among musicological objects one can find spatiotemporal (particular), as well as non-spatiotemporal ones. The second class divides into two subsets: quasi-particular objects (i.e. compositions-ideas) and universal objects (i.e. various theoretical objects as scales, keys and musical forms). Moreover, musicology is a theory of artifacts, what brings about the fact that its domain constantly changes and increases. The specific construction of the domain of musicology is joined with peculiarities of its terminology and conceptual scheme. Musicological terminology is very wide and musicological terms are encumbered by logical errors: ambiguity and vagueness. At the same time, acquiring the state of correctness in such a complicated conceptual and terminological framework is a very difficult task. Another peculiarity of musicology is the fact that one cannot sharply distinguish between analytic and synthetic musicological sentences. Finally, the peculiar feature of musicology is the presence of normative sentences in its structure. A methodologist, concerned with diagnosis of logical status of methodology and methods of its improvement, has to respect all these peculiarities.
