The Book of Psalms name is derived from Greek “the words accompanying music” and is an anthology of individual psalms.  The composition of Psalms is believed to have spanned several hundred years and transcribed from oral tradition.  Many of the psalms are attributed to King David but other authors likely included the family of Asaph, the sons of Korah, Heman, Solomon, Moses, Ethan the Ezrahite.  Several of the psalms contain no credit.
