Midrash su I Re 15:30

Rabbi Reuben said: The entire body follows the head, and when the shepherd goes astray the sheep go astray after him, as it is said, "For the sins of Jeroboam which he sinned, and wherewith he made Israel to sin" (1 Kings 15:30). When the shepherd is good, all follow after him. Moses began to sing, and to utter praises before the Holy One, blessed be He, and all Israel followed him, as it is said, "Then sang Moses and the children of Israel" (Ex. 15:1). Miriam began to sing and to utter praises, before the Holy One, blessed be He, and all the women followed her, as it is said, "And Miriam the prophetess, the sister of Aaron, took a timbrel… and all the women went out after her" (Ex. 15:20). Whence did they have timbrels and chorus in the wilderness? But the righteous always know and conciliate (God), and are assured that the Omnipresent, blessed be He, performs for them miracles and mighty deeds. Before (the time of) their departure from Egypt they prepared for themselves timbrels and chorus.
