Never before has one class been devoted solely to the purpose of examining the piano soundboard as a working, dynamic system. Aimed at piano technicians of all levels, attendees will be able to leave at the end of the day with a broad understanding of how soundboards do what they do to make beautiful music. Topics to be covered include: Ø Tone woods - how woods are selected, processed and assembled into soundboard panels. Wood as an engineering material. Understanding the acoustic properties of wood. Ø The effect of soundboard thickness, tapering, shape, and grain angles on piano tone. Ø The mechanics of the soundboard system. Understanding what ribs do and how they do it. How ribs are designed and sized, and the importance of rib location. Understanding soundboard and rib crown. Creating soundboard crown using the different types of crowning systems. Ø The relationship between soundboard crown and string bearing. How string bearing affects piano tone. Practical methods of setting downbearing on new and old soundboards.

Make Checks Payable to: Sacramento Valley Chapter PTG Bio: Delwin D Fandrich Del began rebuilding pianos at the age of seventeen and, with the exception of three and a half years spent working on various electronics devices while serving in the US Air Force, he has been involved with the inner workings of pianos ever since. While most of his early piano work involved rebuilding or remanufacturing, he also built up a clientele of tuning customers that included the Portland Civic Auditorium and the Oregon Symphony Orchestra. He served as the Piano Service Manager for the Portland, Oregon Steinway dealership for several years which brought him in contact with many of the worldís greatest pianists. It was also a time of increasing frustration with the performance of the modern piano. Long an experimenter, Del became a serious student of piano design. His studies include a wide variety of subjects ranging from basic engineering and physics to piano soundboard acoustics and vibration analysis. He began experimenting with specific pianos purchased for the purpose. In 1985, after working independently for several years he was offered the position of Director of Research and Development at the Baldwin Piano and Organ Company. Returning to the Pacific Northwest in 1990 he designed the new Walter 190 cm (6í3î) grand piano and built the first prototypes of that instrument. Subsequently he has been involved in a variety of different piano design and building projects.
