Full disclosure: I created today's arrangement to try and win a contest. :)
On the Sheet Music Plus website, the top-selling SMP Press song is almost always a piano solo version of Leonard Cohen's "Hallelujah." So, when SMP Press announced a contest for sacred piano solos and trios, I figured, "If you can't beat them...." :)
This arrangement is designed for one beginning student and one more advanced one, with the melody falling primarily into the Primo (easier) part.
