Doesn't music matter the most when it comes to artistry though?
To you, clearly. Others may have different priorities.
It's what all of the artistic criteria stems from.
In the Program Component definitions, you mean?
(Or do you mean that all art, including literature, painting, etc., are all about music??)
Performance
Involvement of the Skater/Pair/Couple physically, emotionally and intellectually as they
deliver the intent of the
music and composition.
*Physical, emotional, intellectual involvement and projection
*Carriage & Clarity of movement
*Variety and contrast of movements and energy
*Individuality / personality
*Unison and "oneness" (PS, ID)
*Spatial awareness between partners
Yes, all these criteria are meant to be demonstrated while delivering the intent of the music (and the composition; see next section), but they don't mention music specifically in the individual bullet points. Is it possible to demonstrate any or all of those criteria with no music playing, or with a generic relationship between the mood of the music and the mood of the performance? I believe the answer to that question is "Yes."
If you can watch a practice session or warmup while no music is playing and single out one or more skaters/teams as artistic in the sense of showing great carriage & clarity or individuality/personality or unison, then doesn't that argue that parts of their artistry are not directly related to music?
And what about someone who, e.g., shows a great emotional connection to the emotion of the music -- dramatic or romantic or lighthearted movement and facial expression to dramatic or romantic or lighthearted music -- but the movements don't actually match the rhythm and the skaters would get dinged for being off time by ice dance judges? But they could still be rewarded for meeting that first Performance bullet point especially well. Is that not artistic?
Composition
An intentionally developed and/or original arrangement of all types of movements according to the
principles of
musical phrase, space, pattern, and structure
*Purpose (idea, concept, vision, mood)
*Pattern / ice coverage
*Phrase and form (movements & parts of the program
to match the musical phrasing)
*Originality of the composition
Looks like music is relevant to 1/4 to 1/2 of these criteria and the other criteria can be easily fulfilled with no music or background music.
"Ice coverage" in the sense of skating fast on deep edges might not be considered an "artistic" criterion, but laying out the pattern and elements of the program in a way that uses the ice surface as a canvas to create a visually satisfying pattern across the time of the program surely is.
Interpretation
The personal, creative, and genuine translation of the
rhythm, character
and content of music to movement on ice.
*Movement and steps
in time to the music (Timing)
*Expression of the
music's character/feeling and rhythm, when clearly identifiable
*Use of finesse to reflect the
details and nuances of the music
*Relationship between the skaters reflecting the
character and rhythm of the music (PS, ID)
*Skating primarily to the
rhythmic beat for the Short Dance and keeping a good balance between skating to the
beat and melody in the Free Dance (ID)
This component is all about the music. But it's only one of the three "artistic" components.
