And it came to pass, when the evil spirit from God was upon Saul, that David took a harp, and played with his hand: so Saul was refreshed, and was well, and the evil spirit departed from him.

The discipline of music incorporates great power and knowledge which brings delight; teachers of secular literature, through the generosity of God who grants all that is useful, have made it possible through theoretical texts to ascertain what was earlier regarded as hidden from view in the nature of the world. The first division of this discipline, then, is into harmonics, rhythmics and metrics. The second division, that of musical instruments, is between percussion, strings and wind. The third division is into six harmonies, the fourth into fifteen tones. In this way the virtue of this most beautiful discipline is unfolded by such distinctions drawn by people of old. We read in secular works that many miracles were brought forth by these measures. But we need say nothing of this fabulous material; we read that by means of David’s tuneful harp the demon was expelled from Saul. The divine reading attests that the walls of Jericho at once collapsed at the din of trumpets. So there is no doubt that sounds of music, at the Lord’s command or with his permission, have unleashed great forces.
