Mass in B minor, BWV 232

No. 12 · Credo in unum Deum

Johann Sebastian Bach · 1748–49 · A major · 45 bars · 91 chords analysed

Bach assembled his monumental Mass at the very end of his life, partly from earlier cantatas, and never heard it complete. Its 24 movements range from five-part choruses with trumpets to intimate arias. This is the full orchestral and choral score.
