J.S. Bach was a brilliant man who believed that God was the reason to compose music. “For God alone be the glory” they found written on his own manuscripts. He was a Christian who would sometimes write at the beginning, “Jesus help me.”
Brilliant man evidence: “Playing and studying Bach convinces us that we are all numbskulls.” — Robert Schumann (one of the greatest composers of all time)
Johannes Brahms (another one of the greatest composers of all time):
“On one stave, for a small instrument, the man writes a whole world of the deepest thoughts and most powerful feelings. If I imagined that I could have created, even conceived the piece, I am quite certain that the excess of excitement and earth-shattering experience would have driven me out of my mind. If one doesn’t have the greatest violinist around, then it is well the most beautiful pleasure to simply listen to its sound in one’s mind.”
Bach’s faith also influenced Christopher Parkening, the great classical guitarist, to pick up the guitar again after early retirement.
