Hark the Herald Angel Sing (Lyrics: Charles Wes­ley, Music: Felix Men­dels­sohn)

Correct as far as I can tell

 3     4   4  -3   4   5   5  -4
Hark! The her-ald ang-els si-ing,
 6    6  6 -5   5  -4    5
"Glor-y to the newborn King;
  3    4   4    -3   4   5 5  -4
Peace on Earth, and mer-cy mi-ld,
 7   6   6   -5   5  -4   4
God and sin-ners rec-on-ciled!"
-6 -6   -6   4  6  6   -5 5
Joyful, all ye nations ri-se,

Join the triumph of the ski-ies;
