1 Chronicles 25:3, 6

From the sons of Jeduthun, there were Gedaliah, Zeri, Jeshaiah, Shimei, Hashabiah, and Mattithiah, six in all. They worked under the direction of their father, Jeduthun, who proclaimed God’s messages to the accompaniment of the lyre, offering thanks and praise to the LORD.

All these men were under the direction of their fathers as they made music at the house of the LORD. Their responsibilities included the playing of cymbals, harps, and lyres at the house of God. Asaph, Jeduthun, and Heman reported directly to the king.
