Piano Regulation
Regulation is the process of making technical adjustments to correct various problems rising from long use and atmospheric changes and to restore the condition of the piano to its original factory specification. Recognizing the need for regulation is difficult since many of these problems slowly accumulate over time. However, a well-regulated piano rewards you with accuracy and smoothness of the touch in every key, easing the technical aspects of piano performance and allowing students to perform with an even touch.
