It started out with several measures of fast and high notes that seemed to lift the vaulted ceilings of the Cathedral straight off of their walls. It was very beautiful and delicate, almost like listening to a harp. And then the bass line kicked in. The low pipes on this organ are bigger around than I am, and when they blast, the bass reverberates through the thick stone walls and you can feel it coarse through your entire body. The sheer contrast of the delicacy of the high notes and the raw power of the lows was awe-inspiring. Nobody moved from their seats or grew restless, despite the fact that the service had ended. It was breathtaking. The organist did his work for at least ten or twelve remarkable minutes, before ending with a ten-second long major-chord that brought tears down my face. Awe-inspiring.
I'd love to know the song, but I don't think that any sound system I'd be able to play it on would do it justice. I will go back next week to see if they can play me another masterpiece.
