1729. Only nine of J. S. Bach's settings are known to have survived (they include the cantatas for Christmas Ehre sei Gott in der Höhe, BWV 197a, New Year Gott, wie dein Name, so ist auch dein Ruhm, BWV 171, Whit Monday Ich liebe den Höchsten von ganzem Gemüte, BWV 174, and the feast of St Michael Man singet mit Freuden vom Sieg, BWV 149) the statement made in the preface has been debated. Reconstructed scores Examples of reconstructions include the funeral music for Prince Leopold and the St Mark Passion (BWV 247) where Bach's music can be reconstructed because it is known to have been used in surviving pieces. Bach sometimes returned to compositions commissioned for one-off occasions and recycled the music. Picander was able to help the composer in this process by providing metrically similar new texts, effectively setting words to Bach's music. References Sources Paul Flossman.
