1 Chronicles 15:19-22

19So the singers, Heman, Asaph, and Ethan were appointed to sound aloud the bronze cymbals;

20and Zechariah, Aziel, Shemiramoth, Jehiel, Unni, Eliab, Maaseiah, and Benaiah [were to play] with harps tuned to Alamoth [that is, a high pitch];

21and Mattithiah, Eliphelehu, Mikneiah, Obed-edom, Jeiel, and Azaziah were to lead with lyres set to Sheminith [that is, the eighth string, a low pitch].

22Chenaniah, leader of the Levites, was in charge of the singing; he gave instruction in singing because he was skilled.
