Johann Sebastian Bach said, “All music should have no other end and aim than the glory of God and the soul’s refreshment; where this is not remembered there is no real music but only a devilish hub-bub.”
He headed all of his compositions: ”J. J.,” the initials for, ”Jesus Juva” which means “Jesus help me.”
He ended them “S.D.G.,” the initials for, “Soli Dei Gratia” which means “To God alone be the glory.”
