I thought I’d share a piece composed for a parish liturgy last year. It seems appropriate for Wednesday’s observance. I adapted the melody from an alleluia in BFW for the September 14th feast:
Somewhere in my files is Litany I, but I never put it into my music software. And as I scanned this and threw it up on this post, I saw a parallel fifth I’d rather avoid, plus the octave hooking back to the invocation. Oh well. If you want to use it, just change the accompaniment.
