Again, the CMAA has outdone itself by providing a great textbook on chant for all ages. Get it here as a free downloadable PDF or buy it for your chapel/parish choir for only US$13 per copy (softcover). With news of the Motu Proprio by the Holy Father liberating the Traditional Mass soon, make sure your parish is ready should your parish priest wants to celebrate that Mass!
