What Are Weighted Keyboards & Why Do Weighted Keys Matter?


We look at the importance of weighted keys, why it matters and 5 of the best weighted keyboards that you’ll love playing

When choosing a piano or keyboard, something that you might be curious about is weighted keys and why weighted keyboards are so sought after.

Certain digital pianos, especially those made by Korg, Roland and Yamaha have been built with a keybed that effectively emulates the feel of an acoustic piano and the ‘weight’ of the keys.

But how does that make the sound?

As acoustic pianos are made with hammers and strings, the hammer strikes the strings, whether that’s one, two or three strings (depending on pitch) which then causes the string to vibrate. This vibration is what makes the noise and what we eventually hear as a note.

The hammer that strikes these strings is connected to the key by a lever type system. This lever has a natural weight or resistance which we can feel when we play an acoustic piano. This weight automatically feels more ‘natural’ when we play a piano and helps us gauge how hard to press or hit the key to get the sound we want. Press softly and the note will resonant softer, press harder and the extra pressure plus the weight of the lever will cause the hammer to hit the strings harder, thus causing a louder sound.

With digital pianos and keyboards, we don’t actually need the weighted keys to get this form of expression, as the computer inside automatically detects how hard and how fast we press the keys, providing the correct sound, and some digital pianos are made with weights built in to the keys to emulate the feel of an acoustic piano. You get all those sound of an acoustic piano without any of the tuning issues and extra weight as well as a whole host of different sounds to choose from.

This is what makes digital pianos with weighted keys so sought after.

Benefits of weighted keys?

Whether we’re talking about weighted keys, semi weighted or even graded hammer weighting, all of these types of weighted keys have their benefits. We’ll get to the different types of keys further down in this blog, but the main benefits of weighted keys all come down to playability and realistic resistance, which encourages more of a dynamic akin to when we play an acoustic piano. If we’re used to playing acoustic pianos, we’ll make an easier transition to a digital piano with weighted keys.

Weighted keys also help in building finger strength which therefore enhances your playing technique overall, encouraging good playing habits.

Not all of us will want weighted keys on our keyboard of course, say for example if you have a small MIDI keyboard that you need to throw in your backpack, the extra weight from weighted keys might not be a good idea, but if you’re a performing musician travelling in a van or your car, it’s definitely worth upgrading to a weighted key option if you like a more realistic feel when playing piano or keyboard.

Essentially weighted keys provide players with the response, feel and dynamics of an acoustic piano.

What are the different types of weighted keyboards

If you’re new to piano or keyboard, its important to understand the different types of weighted keys and weighted keyboards available as this will help you make the right choice when purchasing your keyboard.

There are a few main types of keyboard keys, and the different stages of weighted keys being these 4 levels:

1. Not weighted

Most MIDI keyboards and budget friendly keyboards do not have a weighted action keyboard, however, this can sometimes extend to professional level studio and stage keyboards such as the Roland GO:Keys. When keyboards are not weighted, they do not use weights within the keybed, but will still usually have a touch and velocity sensitive keyboard so you can still enjoy responsive sounds.

2. Semi weighted

Most keyboards just above the ‘beginner’ bracket will have a semi weighted action. This involves a sprung-action key with more resistance than an unweighted keyboard. This provides a playing experience which is far more responsive to your touch. If you can stretch to semi-weighted keyboards within your budget, you’ll feel the difference.

3. Hammer action keyboards

When a digital piano or stage piano states that it has a hammer action keyboard, this means the keys have a mechanism which replicates the same hammer action as an acoustic piano. This is usually achieved by the attachment of a lever system near the key to add more resistance to the keys you’re playing.

4. Graded weighting

Graded weighting is a standard feature on acoustic pianos and some higher-end digital and stage pianos. On acoustic pianos you’ll find that there is more resistance when you play keys in the lower range and less as you make your way up to the upper ranges.

Digital keyboards and digital pianos will require a heavier touch on the low-end notes and a lighter touch as you get higher. These keys are usually individually weighted for added playability and a feel that emulates an acoustic piano. In many cases digital pianos with graded weighting will have keys made from wood rather than plastic. However, some options feature keys that emulate the feel and weight of ivory.

Should I buy a weighted keyboard?

Before you pull the trigger and purchase a weighted keyboard, you need to decide whether you need to stretch your budget to accommodate the extra cost.

You also need to consider your goals and needs as a musician. If you just want something to record with or play live with, and you don’t need the response and feel of an acoustic piano, then you likely don’t need weighted keys.

If you are travelling with your piano frequently, it’s probably a better idea to get a keyboard with either non-weighted keys or semi weighted as these are a lot lighter to carry.

If you are learning to play piano and you are committed to it, you need a piano for around the home or you are going to study music, we’d definitely recommend using a weighted keyboard. As weighted keyboards encourage finger strength, this works in the same as training in the gym. The more you lift the heavier weight, the easier it is lift lighter weights. With that said, if you only play non-weighted keys, your finger dexterity and strength will only be relevant to non-weighted keys and you might find it jarring to play a weighted keyboard. Something worth thinking about when it comes to purchasing your keyboard as unweighted keys won’t help you build the strength to play a concert grand piano.

    Thank you for posting this brilliant blog.
    I am taking my ABRSM grade 4 in six months and was considering upgrading my current digital piano.
    The piano used for the exam has heavier key pressure compared to mine as has my tutors piano.
    It's really difficult to get anywhere near the articulation I can get from my piano when playing on the exam/tutors piano.
    Everyone I have spoken to just says "O yes, digital pianos cannot compare to acoustic" but without explaining "why".
    Thanks again for your research and informative blog.
