A Cathedral of Sound

from NPR ...
The Mass in B minor is as lofty in design, scope and expression as anything written by the hand of man. It's one of several instances in the music of Johann Sebastian Bach in which a piece is created as an ideal type, rather than crafted for a practical use. As such, it represents an attempt to both summarize the tradition of the mass in a single perfect specimen and leave a statement on the nature of sacred music as a bequest to the future.

Most of the work's component parts date from various times in Bach's long residence in Leipzig; they were assembled to form a complete mass only near the end of his life. The earliest section is the Sanctus, from 1724. The Kyrie and Gloria are taken from a 1733 mass that Bach dedicated to the electoral court of Saxony at Dresden. The last major addition was the Credo; the keystone to the whole archlike structure, and itself a wonderfully symmetrical arch, it was written in 1748-49. Bach never heard the work in its entirety, but it represents a collection of movements in diverse styles; the Mass in B minor transcends the inconsistency of its origins.

As I write, I am listening to John Eliot Gardiner's interpretation. Get it here.
