Harmonie ...

In seinem Lied "Halleluja" faßt Leonard Cohen wesentliche Teile der Harmonielehre zusammen:

"I've heard there was a secret chord,
That David played and it pleased the Lord,
But you don't really care for music, do you?

It goes like this: The Fourth. The Fifth. (Die Quart, die Quint)
The minor fall. The Major Lift.    (Subdominante, Dominante)
The baffled King composing Hallelujah..."
...

"Halleluja ...
...
Your faith was strong, but it needed proof ...
..."
