Abstract. "Choral arrangement" is one of the specialty subjects. The main goal of the science "choral arrangement" is to master the theoretical and practical skills of adapting, processing and transmitting choral and solo vocal works for choral ensembles of various composition. This discipline requires in-depth knowledge of the following disciplines: choral studies, music theory, harmony, polyphony, analysis of musical forms. Possibilities of performance, ranges, registers, tessitura of voices; knowledge of the law of cadence and harmonic development, the basics of polyphony; Without knowing the conditions that lead to a normalized ensemble, it is impossible to adequately write a reproduction. The main part of the lessons is the analysis of the studied score, whether it is a choral texture or an instrumental texture. An analysis of the described work will help to better understand the structure of the work, the observation of harmonic and melodic development paths, and the composer's opinion.
