Meeting called to order at 6:41pm. A proposal to restructure chapter communications was discussed. It aims to streamline communications, ensure conflict-free notices, and support the chapter secretary. The solution was agreed upon by the members present, and the restructuring will occur in April. There will be a two week transition period of announcements and reminders to precede the changes and ensure all members are properly notified. More detailed information coming soon.

In this class, Robert first reviewed the fundamental terms and mechanical principles needed to understand action ratios, and then presented a variety of useful formulas for diagnosing issues with the various weights and ratios within an action. Then the process and decisions made while balancing the actions of three different pianos were examined.
Below is a link to the visualizer for down weight, up weight, friction, and balance weights which can be found on Robert’s website. http://springerenterprise.com/dufb.php
