When David appointed Levites to minister before the ark, which instrument did Asaph, their chief, sound?

Answer: Cymbals

Asaph was chief. Others played harps and lyres while Asaph sounded the cymbals, and the priests blew trumpets before the ark.

“Asaph was the chief, Zechariah was second, then Jeiel, Shemiramoth, Jehiel, Mattithiah, Eliab, Benaiah, Obed-edom, and Jeiel. They were to play the harps and lyres, while Asaph sounded the cymbals and the priests Benaiah and Jahaziel blew the trumpets regularly before the ark of the covenant of God.”— 1 Chronicles 16:5-6 (BSB)
