Baldwin's voices are all front sound holes, and they all have the function of four pedals, which is as practical as grand piano's pedal function. There is no need to practice the grand piano specially in the later period, and the unique skill is Baldwin's patented silent skill. The sound is rich and clean. Baldwin's performance is the performance of the vertical price triangle. If you are in Zhengzhou, Henan Province, go back to Xingyi Musical Instrument Store on Erqi Road for comparison.
