Problems of variability of the musical genre reng in the mugham performing arts of youth

Consideration of the variability of the musical genre of rang in mugam performing arts showed that ranks arose and developed in the art of mugam as a form of vocal-instrumental music. Their melodic structure is directly related to the sections of mugam. There are numerous varieties of this relationship. Based on the analysis of the musical notation of the ranks, it was determined that in practice of performing mugam the ranks are directly related to the vocal-instrumental mugam, and this is especially important for their compositional structure. In this regard, in almost every version of mugham destgahs there is a set of different ranks, including tesnifs. The analysis of various musical records of the ranks in the musical performing arts helps to identify the features of the manifestation of this form of folk music in mugam, as well as the further development of this musical genre and musical culture as a whole. We consider it appropriate to study, primarily, the vocal-instrumental interpretation of mugham when studying mugam destgyahs and the melodic interconnections of rangs and tesnifs with sections (shobe) of mugam. After analyzing various musical notations of mugam dastgahs, we were able to trace how rengi relate to mugam shobe. It can be noted that many rengi are used in the recordings of these works associated with various performances in relation to various shobe of mugams. This feature is inherent in various mugham dastgahs – "Shur", "Segah", "Chahargah", "Bayati-Shiraz", "Shushter", "Humayun", etc. All this can be traced in musical notations, as well as in live mugham singing and sound recordings, which helps to determine the numerous variants of rengs related to these mugams. Within the framework of each mugham, dozens of rengs were created and included in musical practice. Part of this rich musical heritage is captured and preserved in sound recordings and sheet music. We believe that it is advisable to study rengi, grouping them into mugham families in order to analyze their musical language and reveal their inherent variability.
