When I attend a performance of the San Francisco Ballet, there is no announcer on stage telling me about the action. "My wasn't that a beautiful lift"! or "Did you notice the corps de ballet was not in unison on that entrance". The same is true for the symphony."The trombones were late in that last passage". "The first flute was out of tune"....etc.
Skating is a combination of athleticism and an aesthetic performance. The artist (skater) is communicating something to those watching. Having an announcer constantly talking, destroys the experience. I want to form MY OWN opinion of the event. I don't need someone to tell me what to think.
Here is my proposal: Have the announcers introduce the event and the skater. Tell us a little about him or her and something about the music that will be performed. Then, when the music starts......SHUT UP. During the replay, make the necessary comments about style, mistakes,and on the elements that were performed beautifully.
I would thoroughly enjoy this approach!
