Johann Sebastian Bach wrote the letters SDG at the bottom of every piece of music he ever composed.
Soli Deo Gloria. To God alone be the glory.
Not just on his church music. Not just on his cantatas and passions and oratorios. On everything. On dance suites. On instrumental pieces. On the exercises he wrote for his children and students. Every single composition carried that dedication — a deliberate, consistent act of attribution that said everything about how Bach understood what he was doing.
He also wrote JJ at the top of most scores before he began. Jesu Juva. Jesus help me.
Every composition began with a prayer and ended with a dedication.
Bach is widely considered the greatest composer who ever lived — a status that even his rivals and critics in his own era struggled to deny. The Well-Tempered Clavier. The Goldberg Variations. The Mass in B Minor. The St. Matthew Passion.
The Brandenburg Concertos. Music of such mathematical perfection and emotional depth that musicians and composers two and three centuries later found it inexhaustible.
What most people don't know is that Bach was also a serious biblical scholar. He owned and annotated a three-volume theological commentary on the Bible — his annotations are still studied by scholars today. His understanding of Scripture was not casual or conventional. He brought the same rigorous intelligence to theology that he brought to counterpoint.
He saw music as a branch of theology. He believed that well-ordered music was a glorification of God and had a practical effect on the soul.
Albert Schweitzer — himself a concert organist as well as a theologian and physician — wrote that Bach's music embodied a relationship with God that was far more profound than what many theologians had managed in words.
