Since you said with such authority that #8 is a NO , I would like to ask you if there is a more detailed official definition in the figure skating world regarding "element matched to the musical structure". I am not saying I am definately right, but to my trained ear, I--a person who had won a piano concerto contest, who had taught piano for living--could not agree with your assertion. Maybe in figure skating, the so-called "muscial structure" has a special definition. I don't know. Can you shed light on it?
Well, first of all, I should state that #8 is an awful criteria for determining the GOE of a jump and needs to be removed from the rules. The placement of a jump in relation to the music is part of choreography and interpretation. It should have absolutely no bearing on scoring the QUALITY of the jump itself. Spins and footwork are different because they last longer (and they also never have to be the same, whereas a Quad or Triple Axel or Triple Lutz, etc, is ALWAYS pretty much the same thing) so it makes more sense that one aspect of judging those elements, especially with footwork, is tied to their musicality.
That aside, if #8 is to be used to give an extra bonus to the GOE of a jump, it should only apply when the jump is used to interpret the music in an extremely special way. Patrick Chan's Quad did not have any special relation with the music.
