Roger, I should have added that I have also taught a number of PTG Convention and Conference classes on the subject of how soundboards work. These have been listed under a number of titles including several under what I call the "Piano Sound Series." These include: "Troubleshooting the Soundboard by Ear" (Analyzing piano tone problems that are caused by the soundboard.) "Soundboard Crown -- What is it & Why Is It There?" (What is soundboard crown? How did it get there? Why is it needed? Where does it go?) "Downbearing -- Theory & Practice" (The above, with more emphasis on theory.) Some of the other classes I've done on soundboards include "Soundboard Maladies -- Are Soundboards All They're Cracked Up To Be? (The subject of the current Journal series.) "How The Piano Works -- From the Forest to the Concert Hall (The soundboard from the tree through to the soundboard. Also the supporting structure -- the rim, belly rail, etc.) Actually I'm doing this class at the California State conference early next year. "Making a Silk Purse Out Of A Sow's Ear" (This class actually does cover some of the modifications that we make to piano soundboards during our redesign process.) "Voicing the Piano Soundboard" (A general class on how soundboards work and how soundboard performance is affected by the rim, plate, stringing scale, etc.) "Taming the Killer Octave" (A class that analysis why we have so much trouble from the killer octave and above.) "The Voice of the Piano" (A general purpose soundboard performance class.) Sadly, there hasn't been much call for classes of this type for several years. The classes are mostly considered to be "too advanced," or not of enough "general interest," or "not practical enough" for the Technical Institute. Ah, well, maybe someday these subjects will, once again, be considered suitable for study by piano technicians. Regards, Del
