I wrote last year, about Holy Week, and about the glorious and mysterious chant, the Pange Lingua.
Sing, my tongue, the Savior’s glory,
Of His flesh the mystery sing,
Of the blood, all price exceeding,
Shed by our immortal King,
Destined, for the world’s redemption,
From a noble womb to spring.
You can hear a wonderful version, in Latin, <a href="http://home.snu.edu/~bballweg/pange/pange.mp3 here (H/T Chant Blog
Beautiful as this is, nothing compares to the great chant of Easter, the Exultet. It is the duty and privilege of the Deacon to sing this glorious, intricate chant and Deacon Greg writes of his ongoing efforts to learn the thing via this particularly good mp3.
