The Caecilia Project

About the project
Sacred music, freely given
The Caecilia Project was founded with a simple goal: a community-driven repository of sacred music in the Roman Catholic tradition, for ease of public use.
The library
A repository of sacred music in the Roman Catholic tradition: from the official Gregorian chant of the Liturgy to sacred choral music — “sacred” in the strict sense in which the Church understands it.
Free to use
Anyone who wants to sing this music shall have it. You are welcome to browse and download the files and use them, free of cost.
The collections
Chant books, newly set
Classic books of chant, retypeset from the original editions so they can be printed, corrected and reused.
