how I finally managed to cinch this one was to number the notes in the tones. I would say outloud: 1,2,3,4... etc ( I wouldn't say etc )
and then the first chunk of notes would be memorized quickly because you repeat them so many times, it then becomes a matter of getting the co-ordination down and avoiding the admonishing roar of disapproval

to help with positioning I'd be directly to the right of the beasty and a body span's length from him so the camera would zoom out comfortably. iirc I'd also use the number pad or something else, there's threads on the simple simon boss posted elsewhere on the forums where other hints are posted ( and I'm sure that I've repeated myself

)
