What Is a Weighted Piano? A Full Guide

by Madonna

Weighted keys refer to piano keys that are designed to replicate the feel and response of the keys on an acoustic piano. Unlike the keys on a traditional electronic keyboard, which are typically lightweight and springy, weighted keys are designed to have resistance and tactile feedback similar to that of a real piano. This means that when you press down on a weighted key, you can feel the weight and resistance of the key, much like pressing down on the keys of an acoustic piano.

Benefits of Weighted Keys

Playing on weighted keys offers several benefits for pianists, particularly those who are learning to play or transitioning from an electronic keyboard to an acoustic piano.


Develop Proper Technique: Weighted keys help pianists develop proper finger strength and technique by requiring them to press down with more force to produce sound. This encourages proper finger placement and hand positioning, leading to more controlled and expressive playing.


Transition to Acoustic Piano: For pianists who eventually plan to play on an acoustic piano, practicing on weighted keys can facilitate a smoother transition. The resistance and feel of weighted keys closely resemble those of an acoustic piano, making it easier to adjust to the touch and response of a real piano.


Dynamic Expression: Weighted keys allow for greater dynamic expression, as pianists can vary the intensity of their playing by adjusting the pressure applied to the keys. This enables them to convey emotion and musicality more effectively in their performances.

Types of Weighted Keys

There are several types of weighted keys found in digital pianos, each offering a slightly different feel and response:

Semi-weighted Keys: Semi-weighted keys strike a balance between the lightness of unweighted keys and the heaviness of fully-weighted keys. They offer some resistance and tactile feedback, making them suitable for players who want a more piano-like feel without the full weight of fully-weighted keys.

Fully-weighted Keys: Fully-weighted keys provide the most authentic piano feel, with each key having a consistent weight and resistance similar to that of an acoustic piano. This makes them ideal for serious pianists who want the closest possible approximation of playing on a real piano.

Graded Hammer Action Keys: Graded hammer action keys replicate the feel of an acoustic piano by mimicking the graded weight and hammer action of acoustic piano keys. The keys are heavier in the lower register and lighter in the higher register, just like on an acoustic piano, providing a more realistic playing experience.

Considerations for Buyers

When purchasing a weighted piano, there are several factors to consider to ensure that you find the right instrument for your needs:

Key Action: Pay attention to the key action of the piano, which refers to how the keys respond when pressed. Look for a piano with a responsive and natural-feeling key action that closely replicates the feel of an acoustic piano.

Touch Sensitivity: Choose a piano with adjustable touch sensitivity, which allows you to control the volume and dynamics of your playing based on how hard or soft you press the keys. This feature is essential for achieving expressive and nuanced performances.

Try Before You Buy: Whenever possible, try out different models of weighted pianos before making a purchase. Pay attention to how the keys feel under your fingers and how responsive the instrument is to your playing style.

Here are some recommendations for weighted pianos that cater to different skill levels and budgets:

Yamaha P-125: This popular digital piano features fully-weighted keys with Yamaha’s renowned Graded Hammer Standard (GHS) action, providing an authentic piano feel at an affordable price point.

Roland FP-30: The Roland FP-30 offers a more advanced key action with its PHA-4 Standard keyboard, which combines the feel of graded hammer action keys with the sensitivity of ivory feel keys for a realistic playing experience.

Kawai ES110: The Kawai ES110 features Responsive Hammer Compact (RHC) action, which replicates the feel of an acoustic piano with graded hammer keys and simulated ivory and ebony key surfaces.

Technical Aspects

In an acoustic piano, the weight and resistance of the keys are created by a complex system of levers and hammers that transmit the force of the player’s fingers to the strings, resulting in sound production. Digital pianos replicate this feel using a combination of weighted key mechanisms, sensors, and sound samples.

Weighted keys in a digital piano typically consist of a weighted mechanism underneath each key, which provides resistance and tactile feedback when the key is pressed. Sensors detect the movement of the keys and transmit this information to the piano’s sound engine, which produces the corresponding sound based on the velocity and intensity of the key press.

Comparison with Unweighted and Semi-weighted Keys

Compared to unweighted and semi-weighted keys, weighted keys offer a more realistic and immersive playing experience for pianists. Unweighted keys lack the resistance and tactile feedback of weighted keys, making them less suitable for developing proper technique and transitioning to an acoustic piano. Semi-weighted keys provide some resistance but may not offer the same level of realism and control as fully-weighted keys, making them a compromise for players who want a balance between piano-like feel and lighter touch.


In conclusion, weighted keys are an essential feature of digital pianos that closely replicate the feel and response of playing on an acoustic piano. Whether you’re a beginner learning the basics or an experienced pianist seeking a realistic practice instrument, weighted keys can help you develop proper technique, expressiveness, and musicality in your playing. By considering key action, touch sensitivity, and personal preference, you can find the perfect weighted piano to suit your needs and elevate your musical experience.
