[Verse 1]
  Am               Dm G    Am 
O come, O come, Em-ma-a-nu-el
    Fmaj7          G     Am
And ransom captive I-sra-el
     Am               Dm  G     Am
That mourns in lonely e-e-exile here
  Fmaj7          G    Am 
Until the Son of God appear

[Chorus]
  C        Am        F     Am 
Rejoice! Rejoice! Em-ma-nu-el
      Fmaj7           G     Am 
Shall come to thee, O I-sra-el

[Verse 2]
  Am                    Dm G       Am 
O come, Thou Dayspring, co-ome and cheer
    Fmaj7            G      Am
Our spirits by Thine Advent here
   Am               Dm  G       Am 
Disperse the gloomy clo-ouds of night
    Fmaj7                G      Am
And death's dark shadows put to flight

[Chorus]
  C        Am        F     Am 
Rejoice! Rejoice! Em-ma-nu-el
      Fmaj7           G     Am 
Shall come to thee, O I-sra-el

[Verse 3]
  Am                Dm G     Am 
O come, Thou Key of Da-avid, come
    Fmaj7         G        Am
And open wide our heav'nly home
     Am                Dm G       Am 
Make safe the way that le-eads on high
    Fmaj7             G     Am
And close the path to mi-se-ry

[Chorus]
  C        Am        F     Am 
Rejoice! Rejoice! Em-ma-nu-el
      Fmaj7           G     Am 
Shall come to thee, O I-sra-el

[Chorus 2]
  C        Am        Dm G    Am 
Rejoice! Rejoice! Em-ma-a-nu-el
      Fmaj7           G     Am 
Shall come to thee, O I-sra-el
