When Paul Steinitz founded the London Bach Society he wanted them to perform Bach’s music. Most musicians in those days played Bach in an exaggerated, romantic style, using large choirs and orchestras, playing with lots of vibrato, and with lots of changes of speed which Bach would not have done. Steinitz wanted to show people how Bach’s works should sound. From 1950 he performed them in German. When more musicians started to learn how to play period instruments he started to use these. In 1952 he conducted the first performance in Britain of Bach’s St Matthew Passion in its complete and original German form. It was all part of a movement which was known as “Back to Bach in its original form”.
