'Musicians' in the Bible

The musicians and Levite family leaders stayed in rooms at the sanctuary and were exempt from other duties, for day and night they had to carry out their assigned tasks.

David told the leaders of the Levites to appoint some of their relatives as musicians; they were to play various instruments, including stringed instruments and cymbals, and to sing loudly and joyfully.

The musicians Heman, Asaph, and Ethan were to sound the bronze cymbals;

David was wrapped in a linen robe, as were all the Levites carrying the ark, the musicians, and Kenaniah the supervisor of transport and the musicians; David also wore a linen ephod.

Moreover, David and the commanders of the army selected for the [temple] service some of the sons of Asaph, Heman, and Jeduthun, who were to prophesy with lyres, harps, and cymbals. The list of the musicians who performed their service was as follows:

All of these were under the supervision of their fathers; they were musicians in the Lord's temple, playing cymbals and stringed instruments as they served in God's temple. Asaph, Jeduthun, and Heman were under the supervision of the king.

The musicians cast lots for their duties, everyone alike, the small (younger) as well as the great (older), the teacher as well as the student.
