<html> Barbara,    A common sales technique, especially for player pianos, is to place a mirror on the floor. It's kinda cool, and seems to reflect sound well, also. Just the occasional problem with some female customer's attire. Not cool. Point is, it might be a lot cheaper to try a mirror, or piece of tempered hardboard, even. (wooo.... there may be a cosmic connection with "tempered" hardboard.... better just call it Masonite) %^) G'dluck, Guy At 03:49 PM 9/27/2004 -0500, you wrote: <blockquote type=cite class=cite cite>Hi all,   Well, I hate to sound like a broken record, bu= t I'm still thinking of possibilities for the huge (3500 seat) auditorium with the lousy acoustics.   The floor of the stage isn't hardwood, but something definitely softer (yet another sound sucker upper).  I have yet to get the piano (Steinway D) on stage, since it's stored in the basement and don't want to haul it up until I have it in reasonable working order.  Although I have gotten the director to agree that the piano will be amplified for performances (yea!), I was wondering about what the pianists can hear of themselves, because in spite of being amplified, they tend to "attack" the piano with every bit of might available.  Now I suppose a monitor of some sorts could be rigged up (no problem for non-classical music) and we're still going to give the lower lid and truck wedges a try, but has anyone ever tried something like a portable dance floor?   Do you think it would bounce the sound up for the pianist to hear?  Would the stage crew hate me for suggesting it?  What's the estimate on how many dozens of homemade cookies & brownies would it cost to win them over?  :-)   Thanks,   Barbara Richmond</blockquote></html>
