For a sound that truly resonates with the listener
In a grand piano, strings and sounds resonate throughout the entire body of the instrument producing a rich reverberation that envelops the listener in sound. Not only are the strings you are playing vibrating, but other strings ring as a reaction to ones you play. This is one reason the piano's sound is so complex and rich.
This phenomenon is reproduced perfectly in the Clavinova through Virtual Resonance Modeling (VRM) which calculates the various states of the strings for each of the 88 notes on the keyboard from one instant to the next. As a result, the Clavinova reflects the limitless number of factors inherent in playing an acoustic piano such as which keys are pressed, the strength with which the keys are played and pedal timing.
