ENAim of the paper is to review the results of systematic acoustic studies of musical scales in Lithuanian traditional songs, conducted by the author of this paper together with a group of his students during the last several decades. The aim of the paper is not only to present the results of acoustic measurements, but also to consider their musical implications. They are fundamentally indistinguishable from the phenomena of music perception – pitch categorization, collision of emic systems, "performance rules", etc. Methodology of the research is a computer-aided systematic approach to the analysis of Lithuanian folk songs with application of software for acoustic pitch measurements, analytical, statistical and historical methods. The scientific novelty of the research is determined by a new approach to studying the laws of Lithuanian folk singing heritage by applying the tools of physical sciences (acoustics) in the field of ethnomusicology and by evaluation of the results from viewpoint of music perception. Conclusions. Relics of equitonics and hybrid frameworks appear in the scales of traditional Lithuanian songs. Such cases are mistakenly perceived as "Ancient Greek" scales. Traditionally, vocal intonations have their own patterns of performance, the manifestations of which can often be mistakenly perceived as chromaticisms. Such conclusions can be obtained only with the possibility of using equipment for acoustic analysis. [From the publication]
