symmetrical frets – frets, the scales of which are based on the equal division of the octave. Like other frets, S. l. are built on the basis of a certain center. element (abbreviated as CE). However, unlike, for example, from major or minor, S. l. are formed not on the basis of a major or minor triad, but on the basis of consonance (or central relations) resulting from the division of 12 semitones into 2, 3, 4 or 6 equal parts. Hence 4 possibilities – 12: 6, 12: 4, 12: 3, 12: 2 and, accordingly, 4 main. type S. l. They are named according to their CE (just as a major is named after its CE – major triad): I – whole-tone (CE 12: 6 = whole-tone six-tone); II – reduced, or low-frequency (CE 12: 4 = smart seventh chord); III – increased, or greater terts (CE 12: 3 = increased triad); IV – tritone (or double mode, the term of B. L. Yavorsky) (CE 12: 2 = tritone). Depending on specific. structures of the scale III and IV types of frets are subdivided into several. subtypes. Theoretically possible division 12:12 gives one more type of S. l. (V) – limiting, but devoid of property. structural and therefore standing apart. Pivot table S. l .:

Theoretical S.’s explanation of l. receive in line with the aesthetic. traditions of the theory of proportions, which puts them in a natural connection with other types of modal systems – the modes of the major-minor system and the Middle Ages. frets. The explanation common to all is that each type of mode, depending on its CE, corresponds to one of the numerical progressions known since antiquity – arithmetic, harmonic and geometric. The numerical series formed by them, which give the CE of each of these systems, are given in terms of the coefficients of the numbers. fluctuations.

S. l. – one of the types of modality (modality) along with pentatonic, diatonic, decomp. kind of complicated frets. S. l. branched off from the common European systems of major and minor (the preforms of s. l. are transposing sequences, equal-tert cycles of tonalities, figuration, and anharmonicity of equal-interval consonances). The first samples of S. l. are random in nature (the earliest, before 1722, in the sarabande of the 3rd English suite of J. S. Bach, bars 17-19: des2 (ces2)-bl-as1-g1-f1-e1-d1-cis1. Use of C L. as a special expressive means began in the 19th century (increased mode and whole-tone scale in the bass Sanctus of the mass Es-dur by Schubert, 1828; increased mode and whole-tone scale in the bass in the opera God and Bayadere by Auber, 1830 , in 1835 post in St. Petersburg under the title La Bayadère in Love; also by Chopin). musical language, and connected with an interest in what is alien to this language.)

Bartok addressed; especially widely and in detail S. l. developed by O. Messiaen. In the music S.’s theory of l. were originally described as special alien modes (for example, in G. Kapellen, 1908, “Chinese whole-tone music” was demonstrated on samples composed by the author as “extreme exoticism”). In Russian theoretical musicology the first description of S. l. (under the name “circular” modulating sequences, “circles” of major and minor thirds) belongs to Rimsky-Korsakov (1884-85); the first theoretical S.’s explanation of l. was proposed by B. L. Yavorsky at the beginning. 20th century From abroad. theorists the theory of S. l. developed primarily by Messiaen (“Modes of Limited Transposition”, 1944) and E. Lendvai (“System of Axes”, on the example of Bartok’s music, 1957).
