Psalm 23 attunement: A protective and gently powerful attunement, distilling the spirit and essence of the beautiful Psalm into an attunement. David, a shepherd boy the author of this psalm and later to be known as the Shepherd King of Israel, writes as a sheep would think and feel about his/her shepherd. “The Lord is my Shepherd” implies a profound yet practical working relationship between a person and the Creator and Savior.
