There is no question. The crown jewel in Bach’s oeuvre is the heavenly B Minor Mass. It represents Bach’s lifelong and tireless artistry as a composer and musician of the highest caliber and is a grand synthesis of his every musical innovation and contribution. Bach began the B Minor Mass early in his career and didn’t finish it until the very end of his life when he had already gone blind. Bach never got a chance to hear a full performance of his magnum opus, but his virtuosity lives on forever with the B Minor Mass.
