I have an antique piano, whoses strings are attached on a wooden frame. So : according to the weather, especially in Belgium where we are known to see the four seasons in the same day, I can have humidity varying from 55 to 80% quite easily. which you can imagine, can raise the piano for more than 50 cents. I wondered </FONT><FONT face=Arial size=2>if I really should </FONT></DIV> <DIV><FONT face=Arial size=2>- put it back in tune, each time, or</FONT></DIV> <DIV><FONT face=Arial size=2>- not touch anything untils it's back to the normal humidity rate, </FONT></DIV> <DIV><FONT face=Arial size=2>- change it only at the seasond change but avoid changing string tension to often</FONT></DIV> <DIV><FONT face=Arial size=2>- just tune it on itself, so that when humidity goes bach to normal, I optionnaly have to returne it on itself but not change the whole opiano tonality ?</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Thank you, </FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Philippe errembault</FONT></DIV></BODY></HTML>
