Grandwork tools and protocols solve the age-old grand regulation dilemma that not all parts of a grand action can be accessed in the piano for service and regulation, but when the action moves out of the piano, differences in how it is supported, plus measuring inaccuracies, result in work that needs correcting back in the piano.

The major benefits of solving this overall problem accrue from many little solved problems that are minor in themselves but that contribute to unacceptable accumulations of error. Collectively, these solutions form the Grandwork System.

This system produces best mechanical results every time and provides exactly the right preparation for voicing.
