This is the Composers Datebook for May 13th. I’m John Birge.

On today’s date in 1875, American conductor Theodore Thomas, a passionate advocate for both old and new music, led the Cincinnati May Festival in the first American performance of J.S. Bach’s Magnificat.

Bach composed this work in 1723, originally for Christmas use in Leipzig, then revised the score in 1733. The American premiere, 142 years after that, was also revised, since the original instrumentation was expanded for large 19th century orchestra and Bach probably would have been astonished at the size of the Cincinnati chorus.

Bach’s Magnificat served as the opener for a Festival performance of Beethoven’s Ninth Symphony. The Beethoven was a huge success, and Cincinnati newspapers reported that “Ninth Symphomania” was breaking out in their city.

The newspapers were less impressed with Bach’s Magnificat. The Cincinnati Commercial Review opined: “The work is difficult in the extreme... most of the chorus abounds with rambling sub-divisions. We considering the ‘Magnificat’ the weakest thing the chorus has undertaken... possessing no dramatic character and incapable of conveying the magnitude of the labor that has been expended upon its inconsequential intricacies.”

Well, whatever they thought in 1875, we suspect American audiences and performers have a gotten a little more used to Bach’s “inconsequential intricacies” since then.
