This is an unusual song from M D Ridge. Her pretty flowing melody is embellished by rhythmic treats — the 4/4 to 6/8 step rewards the practice required.
The text is at spiritandsong, where there is a snippet that starts in Vietnamese. The sheet music can be purchased for download at OCP, where the snippet is all English with the trumpet and flutes going berserk and there is a hint of the harmony line before it fades out.
Youtube has some promising versions ruined by talkative assemblies. I didn’t bother with the harmony line in my backing but these clips give the melody and the descant. She also does the baritone and alto parts if you want to go looking. There isn’t enough of this useful sharing of knowledge and the St Kateri choir is to be applauded.
