These are the men David put in charge of music in the Lord’s sanctuary, ¹  after the ark was placed there.

Heman and Jeduthun were in charge of the music, including the trumpets, cymbals, and the other musical instruments used in praising God. The sons of Jeduthun guarded the entrance. ¹ 

They and their relatives, all of them skilled and trained to make music to the Lord, numbered two hundred eighty-eight. ¹ 

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. ¹
