<HTML><HTML>Greetings,             &nbs= p; I find that tuning lower notes on some pianos (the wire wound ones) I don= t always get clean octaves. There seems to be, and this is only on some pian= os, these extra fast beats.  I try to block out the faster beating freq= uency(ies) and tune using the (the octave's) fundemental, and even when I ge= t that low fundemental "in" there's this annoying faster beating. I am tunin= g the bass mostly by ear!  Am I doing something wrong, or is it just ch= eap wire wound strings? What is causing this? It seems to only happen on the cheaper spinets and consoles, occasionally an= upright or grand will have this problem too, but not as often. Julia, Reading, PA</HTML>
