This version of Silent Night is arranged for piano in C major and involves a lot of movement across the piano. I am not the arranger of this particular sheet music; I merely transcribed what I heard. I liked the faux bells, which I had not heard before in an arrangement of Silent Night. Also, if you did not realize it immediately, use two hands for the 8va 4-note chords, so both hands need to jump around.
The melody of Silent Night has not infrequently been erroneously attributed to famous classical composers such as Mozart or Haydn despite the fact that we have generally known that Franz Xaver Gruber is the composer. To settle the matter, in 1995, newly discovered evidence showed that this extremely popular Christmas carol had its lyrics written in 1816 by Joseph Mohr and its music composed in 1818 by Franz Xaver Gruber. For a funny sort of detail, the original music was slightly different and changed by the 1840s to the common version known today. If you are curious, the Wikipedia for this carol shows the notes of the original version in the History section.
