<HTML>Hi list, As I dip into the vast well of knowledge about pianos that is available = on this list and elsewhere, I am gradually learning how much of the theories= apply to real life situations. I've recently been noticing in many pianos how difficult it can be to ma= tch up the octaves for the last bicords before they change to monocords. &nb= sp;And how pianos, particularly short ones, that have wire all the way down = to the tenor/bass break can sound really thumpy or whiny in that area. &nbsp= ; For instance, I've tuned many 10-20 year old Yamaha G-2s.  On the s= urface, nothing wrong with them, and most of them are in good shape.  B= ut I've always found them difficult to tune(unlike the U-1 and U-3s, which a= re probably the easiest pianos on the planet to tune), and I'm beginning to = wonder about the scaling on them.  Is this a reason they were discontin= ued? I am interested in learning a bit more about scaling.  Not that I p= lan to build the next great piano, but I'd certainly like to gain some wisdo= m in this area.  If anybody has any recommendations for books or websit= es regarding scaling that are not overly math-driven, I'd appreciate it. &nb= sp; Thanks for all your info, past and future, Dave Stahl</HTML>
