I’m a ‘cradle Catholic’, but I’m an Anglophile when it comes to Church music. I LOVE Thomas Tallis, William Byrd, and Ralph Vaughn Williams. When we lived in NJ, I was in a Parish Choir whose director used a hymnal called “Oxford Hymnal”, or something like that. Gorgeous music!
The Oxford University Press puts out quite a number of music books, including a massive Book of Carols and a couple of historical works. It prints sheet music as well.
There are a few likely suspects, besides the English Hymnal itself (which is published by OUP):
We sing from all of these (although the 16th c. anthem book copies keep disappearing, Thou Shalt Not Steal to the contrary notwithstanding :-( )
