This is being resent without the spelling errors that I so carelessly inserted. My apologies to Steinway & Sons and the Pianotech list. Keith McGavern A Note About Soundboards: An important feature found in the Steinway is the design and installation of the soundboard. This system is manufactured in such a way that it is constantly under compression, which prevents the soundboard from relaxing. It is for this reason that compression ridges may occur. Soundboard compression is planned and desirable. Compression ridges are a cosmetic indication that the soundboard has simply absorbed moisture from the atmosphere.
