Piano,Vocal,Voice - Level 5 - Digital Download SKU: A0.1323451 Composed by Adolphe-Charles Adam. Arranged by Bill Walker. Christian,Christmas,Holiday,Religious. Score. 14 pages. Bill Walker Music Publishing #911673. Published by Bill Walker Music Publishing (A0.1323451). This version of O Holy Night has been arranged for Piano and Soprano. A challenging accompaniment but ever so fun to play. This arrangement really allows the vocalist to shine. Arranged in the key of C-sharp major, the highest note the vocalist sings is G-sharp an octave and a half above middle C. I hope you enjoy performing this song as much as I did arranging it. Happy playing and singing!
