Why Not "Jubilation"? Because this collection of music is named after Jubal, "the father of all such as handle the harp and organ," according to the book of Genesis in the Bible. See Gen. 4:21.
As the producers of the CD explain, "Jubal represents the origin of music ... the appearing of the arts in the Biblical order of creation. Music is a natural form of joy and praise, and this album's uplifting blend of voice and instruments has inspired the title."
