The “Vatican II Hymnal” is about as traditional as you can get. If you find it highly ironic (no malice intended, just truth) that a very traditional hymnal is called “Vatican II Hymnal,” you wouldn’t be alone. But I think it’s awesome that the horrid misconceptions about Vatican II need to be cleared up.

Iubilate (Jubilate) Deo was a document released by His Holiness Pope Paul VI after the conclusion of Vatican II that called for a retaining of the Latin music in mass. It outlined some very basic chant settings of the parts of the mass. Much of the stuff can be found here, along with MP3 recordings:

The subject of traditional liturgical music in the Ordinary Form is extremely precarious, and is somewhat in a still… primordial stage. It is certainly gaining lots of momentum, especially in cathedrals and larger parishes, but it is still being developed, or rather, returned to.
The
official music book of the Roman Catholic Church is the
Graduale Romanum. The chants can be quite complex, so an abbey based in France has for many years produced a book called the
Graduale Simplex, which also contains beautiful music. Both books are somewhat pricey, but should be an investment for even any amateur Catholic musician or liturgist, in my humble opinion.
