1 Chronicles 16:4-5, 42

Then David appointed some of the Levites to serve before the Ark of the LORD. They had the job of leading the worship and giving thanks and praising the LORD, the God of Israel. Asaph, who played the cymbals, was the leader. Zechariah was second to him. The other Levites were Jaaziel, Shemiramoth, Jehiel, Mattithiah, Eliab, Benaiah, Obed-Edom, and Jeiel. They played the lyres and harps.

Heman and Jeduthun also had the job of playing the trumpets and cymbals and other musical instruments when songs were sung to God. Jeduthun’s sons guarded the gates.
