Superb playability and feel
A Graded Hammer Standard (GHS) 88-key piano keyboard provides a heavier touch in the low end and lighter touch in the high end, and is similar to the hammers inside an acoustic piano. GHS is great for the aspiring pianist, because practicing with the GHS action builds proper finger technique for playing on an acoustic piano. Additionally, the matte finish of the black keys makes them less slippery when playing for extended periods of time.
Piano sound quality only possible from Yamaha
The YDP-143 has improved on the traditional AWM(Advanced Wave Memory) synthesis to deliver real piano sounds. AWM is a technology that uses digital recordings of sources, such as actual instruments, and allows you to enjoy grand piano reverberation wherever you are.
