The genre of Psalms is Songs and Poetry of all kinds. It is written by multiple authors; David wrote 73, Asaph wrote 12, the sons of Korah wrote 9, Solomon wrote 3, Ethan, and Moses each wrote one (Ps. 90), and 51 of the Psalms are anonymous. They were written over the span of approximately 900 years (Beginning at the time of Moses 1440 B.C. and through the captivity in 586 B.C.).

The Psalms include praises of joy, laments, blessings, and thanksgivings. They are directed at God and they help us to express and communicate ourselves to Him. We read about the Psalmist's emotions from one extreme to another, from praising, delighting in and worshiping God with fervor, to repentance and crying out to Him in despair.
