David was a skilled musician and poet, and he played the harp to soothe King Saul when he was tormented by evil spirits. David's musical abilities and his role as a psalmist also led him to be associated with the worship of God and with the expression of devotion and praise. The image of David playing the harp remains a symbol of the connection between music, worship, and devotion in Western tradition.
