Johann Sebastian Bach

The Mass in B minor (BWV 232) by Johann Sebastian Bach is a musical setting of the complete Ordinary of the Latin Mass. The work was one of Bach's last compositions, not completed until 1749, the year before his death. Much of the Mass gave new form to vocal music that Bach had composed throughout his career, dating back (in the case of the "Crucifixus") to 1714, but extensively revised. To complete the work, in the late 1740s Bach composed new sections of the Credo such as "Et incarnatus est".

It was unusual for composers working in the Lutheran tradition to compose a Missa tota and Bach's motivations remain a matter of scholarly debate. The Mass was never performed in its entirety during Bach's lifetime; the first documented complete performance took place in 1859. Since the nineteenth century it has been widely hailed as one of the greatest compositions in musical history, and today it is frequently performed and recorded. Carl Philipp Emanuel Bach archived this work as the Great Catholic Mass.

On 1 February 1733, Augustus II Strong, Polish King, Grand Duke of Lithuania and Elector of Saxony, died. Five months of mourning followed, during which all public music-making was suspended. Bach used the opportunity to work on the composition of a Missa, a portion of the liturgy sung in Latin and common to both the Lutheran and Roman Catholic rites. His aim was to dedicate the work to the new sovereign Augustus III, a Catholic, with the hope of obtaining the title "Electoral Saxon Court Composer”. Upon its completion, Bach visited Augustus III and presented him with a copy of the Missa, together with a petition to be given a court title, dated July 27, 1733; in the accompanying inscription on the wrapper of the mass he complains that he had "innocently suffered one injury or another” in Leipzig. The petition did not meet with immediate success, but Bach eventually got his title: he was made court composer to Augustus III in 1736.

In the last years of his life, Bach expanded the Missa into a complete setting of the Latin Ordinary. It is not known what prompted this creative effort. Wolfgang Osthoff and other scholars have suggested that Bach intended the completed Mass in B minor for performance at the dedication of the new Hofkirche in Dresden, which was begun in 1738 and was nearing completion by the late 1740s. However, the building was not completed until 1751, and Bach's death in July, 1750 prevented his Mass from being submitted for use at the dedication. Instead, Johann Adolph Hasse's Mass in D minor was performed, a work with many similarities to Bach's Mass (the Credo movements in both works feature chant over a walking bass line, for example). Other explanations are less event-specific, involving Bach's interest in 'encyclopedic' projects (like The Art of Fugue) that display a wide range of styles, and Bach's desire to preserve some of his best vocal music in a format with wider potential future use than the church cantatas they originated in.

The piece is orchestrated for two flutes, two oboes d'amore, one natural horn (in D), three natural trumpets (in D), timpani, violins I and II, violas and basso continuo (cellos, basses, bassoons, organ and harpsichord).
