Okay, I think the second paragraph could use some work, considering it was quite difficult for me to puzzle out. Maybe:
One chord without mate and meter played on through the air. An assembly of black waist coats and pink chiffon all stared, struck dumb by the resonating tone from the pianist on the stage, a single woman in gray.

I dunno if that’s quite what you meant to say, but that’s the best I could do. I really like the third paragraph, the descriptions of the way the people lived were really cool, especially “temperature controlled homes.” =]

That is much better. Thanks! ^. I wrote it so fast and I’m guilty of posting without much editing.
