The interaction and interplay of the hammers, dampers, and strings inside a grand piano respond to the subtlest nuances of your touch, creating a limitless range of tonal expression. "Touch" refers to control, not only of intensity (softness/loudness) in playing and releasing the keys, but also of the speed and depth with which the keys are pressed. The Grand Expression Modeling introduced in the CSP-200 Series translates the widely varied input from your fingers into the same limitless tonal variation of a grand piano.
This makes it possible to vary the output by playing the keys to different depths and with different speeds, even when using techniques such as trills or legato, or emphasizing the melody over the accompaniment. Grand Expression Modeling excels at faithfully reproducing the output expected of these techniques in many well-known songs. In Debussy’s “Clair de Lune,” for example, a loose touch creates the faint tone that makes the melody stand out more crisply. In Liszt’s “Un Sospiro,” the accompanying arpeggios accent the melody without overwhelming it, and varied expression of the melody gives it the same quality as vocals. In the last of the Chopin nocturnes, trills, legato, and other delicate techniques where fingers seem to float over the keys deliver the airy, smooth tonal expression required. Playing such pieces on a highly expressive piano helps the pianist learn various techniques and experience the same joy of expression as a painter, but through sound.
