Teaching the founders of Hasidism regarding musical aspects of the God service appeal to two types of Jewish religious teaching: traditional rabbinic texts continues the tradition of the Talmud and the secret Torah of the Kabbalists. The main objective of the proposed study is to elucidate the principles of co-existence of these lines of rabbinical thought in the teachings of Besht and his followers. The results suggest that both approaches are recognized as equal. The reality of both Talmudic and Kabbalistic texts can be elected as the object of the believer`s experience. Immersion into each of them allows you to maintain communication with the Creator at the appropriate level and make influence on His decision. At the same time, melodies from the heaven are an instrument of power of the Creator over all people including the powerful tzaddikim. It should be noted, that consideration of the role of music in the approval of the tzaddiks authority, play a crucial role in the justification of the proposed hypothesis. Since the activities of the tzaddik means to get visible results in this world, the details of the algorithm of his actions and his expression are extremely important. This situation, in its turn, reveals a hierarchy of concepts in the teachings of the founders of Hasidism.
