Douglas Adams is more descriptive of Bach than any other writer I know of.

"A single tune danced through his mind and all his attention rested upon it. It was a tune that seethed through the magical flood, shaped it, formed it, lived through it hugely, lived through it minutely, was its very essence. It bounced and trilled along, at first a little tripping tune, then it slowed, then it danced again but with more difficulty, seemed to founder in eddies of doubt and confusion, and then suddenly revealed that the eddies were just the first ripples of a huge new wave of energy surging up joyfully from beneath."

Adams stated that this was his personal "absolutely perfect" piece of music, and that he listened to it "over and over; drove my wife completely insane".
