==================================================

[Verse 1 (the hush -> the command -> the King comes in -- slow 12/8, pp legato, building)]
  1 1 4    (Creation waits in deep and holy yearning,)
  1 1 1    (through every age of shadow, cold, and night;)
  6m 4 5    (through darkened years the faithful hearts kept burning,)
  1 1 1    (for One long-promised, hidden yet from sight.)
  1 5 1    (Take heart, take heart, ye long-awaiting mortals--)
  2m 4 1    (the watch is done; let heaven's song begin!)

[Climax (the "Fall on your knees" octave leap -- ff, sustained high peak)]
  1 1 4    (Lift up your heads! Ye everlasting portals!)

[Verse 2 (the awed question -> the mighty answer -- back to reverent legato)]

  b6 b3 b7    (that everlasting doors should yield the way?)
  b3 4 b7 b3    ("Who is this King of glory?" -- nations wonder,)
  b6 1 b6    (the very heavens lean to hear this day.)
  3m b3 4 b6    (Then hear the answer break, and tell the story--)
  b3 b6 b3    (the earth's reply resounds from sea to sea:)

[Second Peak (the mighty answer -- soar, then begin the descent)]
  b6 b3 b3 b3    (The LORD, the strong and mighty, comes in glory,)
  b3 1 1    (the LORD of hosts, in battle mighty, He!)

[Tag (decrescendo to a whispered, awed close)]
