BACH AND THE GLORY OF GOD
J. S. 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 his compositions: "J. J." "Jesus Juva" which means "Jesus help me."
He ended them "S. D. G." "Soli Dei gratia" which means "To God alone the praise."
