About the event
Hands on Training course with David STANWOOD
-An Exceptional Event-
David Stanwood presents the Stanwood New Action Protocol, also known as SNAP. It’s his empirically derived, workbench friendly, and computer free method for producing pianos of the highest possible quality by smooth scaling hammer strike weights and key front weights to achieve a desired balanced weight level with an expected dynamic playing quality. SNAP method is Stanwood’s ultimate model for the world. Designed for factory production or aftermarket workshop customizing.
9 Participants will work together analyzing and improving the touch and tone of three late model concert grand piano actions with SNAP method:
Steinway & Sons - D 274 - Hamburg, Germany
Bösendorfer - 280 - Vienna, Austria
Yamaha - CFX - 275 - Hamamatsu, Japan
The event is organized by FJV Piano Design®
It will be held in Puidoux, VD Switzerland March 9-13
This is the kick off training course for the new educational institution:
Stanwood Precision Touch Design® International
Fee
The registration fee is CHF 1,100.00 (approximately USD 1,375.00 or EUR 1,180.00).
Payment can be made online by credit card once the registration has been accepted.
These fees do not include accommodation, meals, or travel expenses, which remain the responsibility of each participant individually.

About the teacher
David Stanwood graduated from the North Bennet Street School in 1979. In the early 1990s, he invented Touch Weight Metrology, the first fundamental measurement system for piano touch, based on his Equation of Balance. This breakthrough isolated core components of keyboard function in ways previously thought impossible and led to his award-winning Precision Touch Design method. Stanwood’s work employs customized tools and techniques to build a piano action tailored to a pianist’s individual needs and artistic goals. His development of the Equation of Balance, and Precision Touch Design - simplified into the SNAP method, represents his lifetime achievement. Together, these innovations open new pathways in the art and craft of piano making, empowering piano builders worldwide. Pianos balanced using Stanwood’s methods are widely recognized for their flawless and responsive playing characteristics.
Awards: On June 1, 2007 Stanwood was presented with the Distinguished Alumni Award from the North Bennet St. School for his contributions to the craft of piano technology. In 2009 he received the Crowl-Travis Member of Note Award from the Piano Technicians Guild. In 2019 he was inducted into the Piano Technicians Guild Hall of Fame.
