What You'll Learn

GHS action is aimed at beginners
GHS, or Graded Hammer Standard, is an action type commonly found in entry-level Yamaha digital pianos. It is aimed at beginners who want to get accustomed to the feel of an acoustic piano. GHS offers solid weighted key action, simulating the experience of playing an acoustic piano. This graded, weighted touch is recommended by piano teachers for beginners to build proper finger technique.
The Yamaha P-143, for example, features GHS action and is one of the lightest 88-key portable pianos available, costing around $500. The Yamaha P125 is another example of a piano with GHS-weighted action, offering a realistic piano feel.
GHS is not the only type of action available. There are several factors to consider when choosing a digital piano, including size, weight, and features. Weighted keys and graded hammer action are two important considerations that affect the keys' feel. Weighted keys mimic the feel of an acoustic piano, while graded hammer action provides a more realistic playing experience.
Graded hammer action, as the name suggests, involves keys that get progressively heavier as you press them down. This means that when you press a key, the hammer gets heavier and hits the string harder, resulting in a louder sound. This graded action is designed to simulate the natural feel of a grand piano.
While GHS action is a great option for beginners, more advanced players may prefer a more refined action type. For example, Yamaha also offers the Graded Hammer 3 (GH3) or Natural Wood X (NWX) actions, which offer an even more realistic and authentic touch.

GHS recreates the feel of an acoustic piano
The Graded Hammer Standard (GHS) action incorporates real hammers and is found on many Yamaha digital pianos, including ARIUS PDP Series and Portable P-Series and DGX-Series models. GHS recreates the feel of an acoustic piano by delivering a graded, weighted touch, similar to what piano teachers recommend for building proper finger technique.
The graded action means that the keys get progressively heavier as you press them down. This is akin to the experience of playing an acoustic piano, where the strings are thicker towards the bass end and thinner for the treble keys. The thicker the string, the harder it is to press down the key. This graded action also allows for a more nuanced and dynamic playing experience, with the ability to play piano pianissimo or forte fortissimo and anything in between.
Yamaha's GHS-weighted action, therefore, provides a realistic piano feel. The weight is generally added to the bottom of the key, so when pressed, the key will sink a bit before coming back up. This graded hammer weighting simulates the natural feel of a grand piano. The GHS action is ideal for beginners who want to start getting used to the feel of an acoustic piano and building their finger technique.
It is worth noting that the "feel" of an acoustic piano can vary depending on the brand and model, and even individual instruments can be adjusted by skilled technicians to change the resistance encountered when playing. As such, the GHS action may not perfectly recreate the feel of every acoustic piano, but it provides a solid foundation for beginners to develop their skills.

GHS uses graded hammer weighting
Graded Hammer Standard (GHS) is a type of keyboard action found on many Yamaha digital pianos, including ARIUS PDP Series, Portable P-Series, and DGX-Series models. GHS uses graded hammer weighting, which means that the keys are weighted to simulate the feel of an acoustic piano. The weight of the keys increases as you move down the keyboard, with the lower keys being heavier and the upper keys being lighter. This graded weighting provides a more realistic and natural playing experience, as it mimics the feel of an acoustic piano, where the strings are thicker and require more force to press down on the lower end, while the strings are thinner and require less force on the treble keys.
The GHS action incorporates real hammers, delivering a graded, weighted touch that piano teachers recommend for building proper technique. This feature is especially beneficial for beginners who want to get used to the feel of an acoustic piano. While GHS is commonly found in entry-level Yamaha digital pianos, it offers a solid weighted key action that provides a realistic piano feel.
The Yamaha P-143, for example, features a Graded Hammer Compact (GHC) key action, which is a variation of GHS. This model is one of the lightest 88-key portable pianos available, offering a slim and compact design. Despite being an entry-level piano, the Yamaha P-143 provides a realistic piano experience and is well-liked by many users.
It is worth noting that different companies have varying interpretations of how an acoustic piano is supposed to feel, and personal preferences may play a role in the choice between weighted keys and graded hammer action. While some prefer the familiarity and comfort of weighted keys, others appreciate the more realistic playing experience provided by graded hammer action. Ultimately, the best digital pianos combine weighted keys with graded hammer action to create the most authentic piano-playing experience.

GHS is found on Yamaha digital pianos
Yamaha has been building acoustic pianos for over a century. This experience has allowed the company to develop a range of innovative keyboard actions for its digital instruments. One such innovation is the Graded Hammer Standard (GHS) action, which is found on many Yamaha digital pianos, including the ARIUS PDP Series, Portable P-Series, and DGX-Series models. GHS is an entry-level graded hammer action that offers a solid weighted key action that simulates the feel of an acoustic piano.
The GHS action incorporates real hammers and graded hammer weighting, which means the lower keys are heavier than the higher ones. This graded weighting mimics the natural feel of a grand piano, where the strings for each note are slightly thinner and shorter in the treble register and thicker and longer in the bass register. As a result, there is greater resistance when playing low notes, requiring a heavier touch with the left hand, while high notes require a lighter touch with the right hand.
The GHS action is well-suited for beginner pianists as it provides a more realistic playing experience than non-weighted or semi-weighted keys, which are typically found on synthesizers or keyboards. These typically use a "spring" mechanism and do not offer the same level of finger technique development as fully weighted keys. With GHS, Yamaha has created a weighted key action that is heavier and an improvement over what is found on non-weighted keyboards.
Yamaha's GHS action is ranked as the company's lowest level of key action, followed by the GH/GHE and GH3 actions found on mid-level and top-end pianos, respectively. As you move up Yamaha's piano range, the key action becomes more akin to that of an acoustic piano, with the most expensive models using the same action and even incorporating wooden keys for an ultra-realistic playing experience.
