With the P-series, which is designed in Europe, Yamaha mainly focuses on the European market. The P121 has a European soundboard, and the improved spine structure contributes to a very rich and expressive tone. Generally speaking, the P121 should score considerably better in the long term than any other piano from the B-series, mainly because of its standard size and solid action.
SH2 Silent System
When the silencing function is activated and the keys are struck, hammer shank stoppers move into place to prevent the hammers from striking the strings. While the piano is outwardly silenced, the movement of the keys and other performance information are picked up by optical sensors and converted to digital data by a tone generator. The digitally sampled acoustic sound is then sent to the stereo headphones for the player to enjoy in complete privacy.
