the P-225 features a much shorter and thinner body design with a compact style. This model looks beautiful from any angle, and blends in well with any room. To achieve a smaller product chassis, we developed the new GHC (Graded Hammer Compact) keyboard (88 keys), which is built to uncompromising standards and offers the same weighted acoustic piano-like playing feel as the GHS (Graded Hammer Standard) keys used in previous models in the P Series.
