Graded Hammer Technology

One of Yamaha's premium weighted actions provides greater accuracy for faster repetitive passages required by intermediate and advanced pianists. Professional-grade components provide a smoother, quieter mechanism when striking the keys.

Well suited for the beginner pianist and delivers the graded, weighted touch piano teachers recommend for building proper technique for playing acoustic pianos.

It's like GH / GHE but also swings back faster, like high-quality piano keys. GH3 allows the player to feel the weight of the key when depressed a second time, even when the player has not completely released the key after the first push of the key.
