But here in Norway we run about 70 % RH in the summer months, and are down around 20 - 25 % in the winter. Small variances around the country really, with the inland areas in general being a bit more dry, and in the winter time colder. <blockquote TYPE=CITE> The other thing I was wandering about is to know when should be the best moment to tune pianos in musicschools(they ask their pianos should be tuned only once a year and no Dampp-Chasers)It looks to me that some pianos have a great pitch drop in the middle section after New Year, so those should certainly be tuned twice?In the Piano Book, Larry Fine says that tuning pianos twice a year is not ideal (to much pitch adjustments)Thanks for any comments, Pierre Gevaert,Belgium</blockquote> I like to tune schools in late September here, as we are well into the fall season and pianos have already moved well into that climate condition. Seems to work pretty well. Tho as most schools dont tune more then once a year they end up having to live with pretty sour pianos in the winter months, while in the middle - late spring they (the pianos) "come back" a bit and sound better. I do not aggree with the argumentation that a piano suffers from being tuned twice a year on two counts. Number one,  minor pitch adjustments can hardly be of any real consequence to the instruments life compared to other determinant factors, and number two.... if one insists otherwise it is perfectly feasable to float pitch in most (98% ??) situations. Further there are other ways of dealing with pitch changes and related stability issues such as Damp Chasers and the like. I tune two schools that I have on contract 4 times yearly. Gives me plenty of time to also pay adequate attention to other aspects of the pianos function. Cheers RicB       -- Richard Brekne RPT, N.P.T.F.
