Bach "Hallelujah, Amen" source
Date: January 22, 2014
In my library I have a Boosey and Hawkes-published anthem, attributed to Bach, simply entitled "Hallelujah, Amen." It's in E-flat, fugal, with the accompaniment doubling the voices. There is nothing on the score that indicates the original source. It's most likely a closing movement from a cantata, but I'm wondering if anyone knows the original source. It is arranged by Walter Ehret; it could even be an instrumental piece.
