The Book of Samuel calls David a skillful harp (lyre) player and "the sweet psalmist of Israel." Yet, while almost half of the Psalms are headed "A Psalm of David" (also translated as "to David" or "for David") and tradition identifies several with specific events in David’s life (e.g., Psalms 3, 7, 18, 34, 51, 52, 54, 56, 57, 59, 60, 63 and 142), the headings are late additions and no psalm can be attributed to David with certainty.
