The crowning glory of Bach's achievements in sacred music, the Mass in B Minor represents a powerful statement of Christian faith. Composed over more than two decades, this unprecedented work pairs deliberately archaic polyphonic sections with far-sighted modern ones, creating a vast, symmetrical plan of almost theatrical proportions. Scored for five solo voices, chorus, orchestra, and continuo, this towering masterpiece is reprinted here from the authoritative Bach-Gesellschaft edition. The work appears in full score, with bar-numbered movements and ample margins at the bottom of each song page for notes and analysis. Ideal for study in the classroom, at home, or in the concert hall, this affordable, high-quality, conveniently sized volume will be the edition of choice for music students and music lovers alike.
I have, and have read, this Dover edition. Unfathomably, it's listed on Goodreads as being interchangeable with a modern Bärenreiter critical edition, whereas this one is a reprint of the Bach Gesellschaft (1856) edition (probably; it might even be a reprint of the first edition (Simrock) of 1845, but I'm pretty sure that like most of the Dover Bach reprints, it relies on the BGA series). Such things should be separated by content, but nothing's perfect...
Kudos to Dover for providing an inexpensive but handsome score for the Bach B Minor Mass. I once had a poster size photocopy of one of its pages hanging in my dorm room 20 years ago.
