I am currently looking for audio Gregorian chant accompaniments on organ for certain Gregorian chant hymns. I've tried searching through the website, but all I could find was propers for Sunday Mass, not including sequences for special feast days and such. In particular, I have in mind "Jesu Dulcis Memoria", the solemn tone "Salve Regina", "Dies Irae" or any other similar chants. Keep in mind that I don't need the scores, just the audio. Any help would be much appreciated. God reward you!
