The Levites were those who were in charge of worship for the Hebrews. The Levites were supported by the tithe as they did not have an inheritance in Israel, so the answer to your question is yes they were paid.
MUSIC
6. In Religious Reformations: We are told by the same authority that every reformation of religion brought with it a reconstruction of the temple chorus and orchestra, and a resumption of their duties. Thus when Hezekiah purged the state and church of the heathenism patronized by Ahaz, "he set the Levites in the house of Yahweh with cymbals, with psalteries, and with harps" (2 Chronicles 29:25). The same thing took place under Josiah (2 Chronicles 34). After the restoration-at the dedication of the Temple (Ezra 3:10) and of the walls of Jerusalem (Nehemiah 12:17) - music played a great part. In Nehemiah's time the descendants of the ancient choral guilds drew together, and their maintenance was secured to them out of the public funds in return for their services.
