Re; Blues / orchestration / crescendo...
When I say say blues, I don't necessarily mean jazz blues (although although I'd certainly include them) ... and
early blues ,say one or two people with guitars .. is no more
real than say, B.B.King with a bass , piano ,drummer, and a couple of horns . ( I wouldn't suggest the idea to B.B. , anyway .)
I simply mean how many instruments are playing at once , are they playing softly or loudly , and so on .. either way , it could be musicians playing from a written arrangement , or musicians improvising..they can achieve a "building" effect without necessarily changing tempo.
You can consider Temptation whatever you want , I guess..but Tom Waits wrote it and plays it as a rhumba ... it's not your standard latin rhumba , but the rhythm is definitely there , and it's not a blues ballad ..a jazz torch song in a rhumba rhythm ?..By any name , it worked.
Though I think V/M could handle a ballet theme well , count me among those who doesn't much care for tutus on ice.

..But I never feel that using ballet music , or even a theme from a particular ballet requires that you tell the whole story in 4 mins. and that the costume has to echo the ballet costume. It's OK if it adapts well for ice dance , but often , it won't.
In the case of Carmen, I actually
would love to see an ice dance friendly version of Carmen's corset from the Petit ballet ( there could be a tiny skirt attached , like a ruffle or two deep) ...but I don't imagine I'll get my wish.
I've always hoped to see them do a Tango FD , since I don't think there's a couple skating today who could do it as well ( only Max Shabalin had a comparable feeling for Tango ) ... but I don't think I'll get to see that , either, now... I think I'll go have a glass of wine ...
