We speak of the Psalms as the Psalms of David. He has been considered the principal writer. He gives the keynote and his voice rises highest in the sacred choir.
But there were other authors besides him. Seventy-three of the 150 Psalms are assigned to him; fifty are anonymous. Psalm 90 is written by Moses. Two are written by Solomon-Psalms 72 and 127. Besides these, Asaph, David's choir leader, the sons of Korah, a family of official musicians, and Jeduthun wrote some. [H.C. Mears]
