'Director' in the Bible

Mattithiah, Eliphelehu, Mikneiah, Obed-Edom, Jeiel, and Azaziah were to play the lyres according to the sheminith style, as led by the director;

Chenaniah, music leader for the descendants of Levi, served as music director, because he was expert at it.

David wore a robe made from fine linen, as did all of the descendants of Levi who were carrying the ark, the singers, and Chenaniah the music and choir director. David also wore a linen ephod.

Their director Asaph played cymbals, and next to him was Zechariah, followed by Jeiel, Shemiramoth, Jehiel, Mattithiah, Eliab, Benaiah, Obed-edom, and Jeiel, who played harps and lyres.
