Stanwood Piano Touch Weight Metrology

David Stanwood talks about his new approach to analyzing and improving the way pianos play. This is a snippet from the Annenberg Network video on Algebra, produced by WGBH Boston. Officially available at: http://www.learner.org/courses/learni... One omission that was accidentally left out of the final edit concerns the Hammer Weight Graph of the Hamburg Steinway showing a big dip in the weight of the graph. In practice, these dips are eliminated by adding or subtracting hammer weight to create a smooth dynamic quality to the action and tone. Similarly the video shows the key weights being smoothed out.
