This summer I bought an alto recorder. I haven't done much with it yet, so I thought I'd try recording a hymn tune with it. Since it's Advent now, I did "Nun komm, der Heiden Heiland," the tune to which "Savior of the Nations, Come" is sung. This is also the tune I started with when I began re-learning how to read music seven years ago.
I followed the arrangement in The Lutheran Hymnal (in which "Savior of the Nations, Come" is #95). The higher two voices are on soprano recorder; the lowest is on alto.
