Well here is that chord in blog format...
Here are the chord changes to the very popular song "Hallelujah" by Leonard Cohen.
The B7 chord (in this key) only makes one appearance in the form of the song, but the impact is striking. It is easily the most memorable chord in the song. The fact is the B7 chord doesn't actually belong in the the key of the song (G). It is borrowed form another key and that is why it is such a special sound.
I've heard there was a secret chord
G EmThat David played, and it pleased the Lord
C D G D
But you don't really care for music, do you?
It goes like this
The fourth, the fifth
The minor fall, the major lift
D B7 Em
The baffled king composing Hallelujah
C G D G
Try applying a finger style pattern like this one over this song...
