Mass in B minor, BWV 232

No. 14 · Et in unum Dominum

Johann Sebastian Bach · 1748–49 · G major · 80 bars · 172 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.
