Arab. theorists have learned Greek. the doctrine of tetrachords and their types, however they brought in creatures. adjustments. The Greeks regarded the gamut as a sequence of downward sounds, among the Arabs, on the contrary, it was melodic. the scale is built in ascending order. In this regard, a different concept of Greek has developed. theories of moods (in Arabic - “jeans”), i. e. frets within a quart (tetrachord). These innovations are especially tangible in chromatic. mood. Greeks more often have small intervals at the lower limit of the quart, Arabs - at its main. tones, leaving a wide spacing in the middle. This type of inclination is called eastern chromatism. The structure of the tetrachord: a - among the Greeks; b - among the Arabs. The theory of moods was developed in the writings of al-Farabi, Ibn Sina. The latter, proceeding, apparently, from theoretical. Ptolemy’s assumptions (commented on by Porfiry, 260 AD), calls 16 moods (genres): 7 “strong” and 9 “weak” (among them - chromatic. , 3 enharmonic). The intervals between the steps of the tetrachords of these inclinations can be located three different. wayswhich, together with derivatives from such combinations, gives 48 inclinations.
