Shania Twain - Forever and for Always (Green Version)

COMM (from the Greek. Komma, lit. - segment). 1) A very small interval between two close-in-height sounds produced by summing various pure intervals and subsequent octave permutations. Pythagorov K. arises when building a sound system from pure fifths and octaves; it is formed, for example, between the sound c2 and the sound his1 obtained using 12 moves from c by pure fifths. This K. is characterized by a frequency ratio of 531441/524288 74/73 and is equal to 23.5 cents (about 1/9 of a whole tone). A synthonic, or didimova, C. arises between a third, constructed with four moves in pure fifths, and a pure large third; it detects a frequency ratio of 81/80 and is equal to 21.5 cents (about 1/10 of a whole tone). K., that is, “difference intervals”, are also formed when constructing sounds using other combinations of intervals (eg, Septimova K.- when building a sound system of octaves, thirds and natural septima). Only a uniformly temperated system is free from K.'s appearance (see Temperament). 2) Sign in the form of a comma (lat. Comma), which in the music notation wok. Op.and op. for wind instruments, there are places where the performer can take a breath, despite the absence of a written pause. Sometimes, with the help of K., backlash pauses are also indicated.
