Our Best Guide To Digital Piano Keys

Digital pianos are becoming a more popular option in comparison to traditional pianos thanks to their affordability and high-quality elements of piano sound which make them sound like the real deal. 

But if you are making a switch from traditional pianos to digital pianos then you might be wondering just how different they are to play with. For keys, higher-end digital pianos have the standard 88-key digital pianos set up just like an acoustic piano. 

To find out more about how the keys work on a digital piano, different key set-ups available, the types of higher-end digital pianos on the market and how they match up to acoustic pianos, we have put together a comprehensive guide below that will tell you all you need to know.

How Do Digital Pianos Work? 

First of all, before we get into more detail about the type of key set-ups you can look for on your digital piano and the different types of keys to choose from out there, it's a good idea to understand how these digital piano type models work and their functions. 

Digital pianos are similar to piano keyboard types except they come with weighted keys and an 88-key setup unlike your standard keyboard, behind each key are samples that produce acoustic replica tones, making these pianos nicer to play for an experienced piano player. 

The samples on a digital piano are recorded straight from an acoustic piano and make different velocity tones according to the acoustic piano sound key you press, the more expensive your digital pianos, then the better these samples will sound as your piano will likely come with more memory to store different sounds. 

We will list the main functions/terms you might encounter when looking at a digital piano for the first time down below. 

  • Keyboard - The keyboard on a digital piano operates with weighted keys and variable sensitivity to have hard or soft playing on the digital keyboard. This replicates how traditional pianos sound. 
  • Circuit panel - This part of your digital keyboard translates the signals into sounds when the piano keyboard is pressed, the circuit panel of your digital piano should never be kept in a damp place to protect it.
  • Pedals - Digital pianos that are attached to a frame like acoustic pianos will come with three standard pedals. The soft pedal is used for playing softer notes, the damper pedal for sustained notes and the sostenuto pedal for quieter notes.
  • Functions - One of the best parts about digital pianos are the wide variety of functions that they come with, these functions include keyboard split options, layering keys, transposing and sequencer functions.
  • MIDI - A MIDI function on your digital piano allows you to connect the piano up to external software via its port. This means you can transfer new sounds or play the electric piano with software.
  • Polyphony - Polyphony is a term on digital pianos which refers to the number of notes you can make on your piano, a great number for a digital piano is around 64.

Different Key Sets On Digital Pianos 

Not all digital pianos have the 88-key piano set up, you can also buy types of digital pianos that have a 32-key setup, 36 and 37 key setups. These types of electric piano tend to start with a C or F note due to the setup. 

Digital pianos can come with longer electronic keyboards too which go from 49, 54 and 61, these types of keyboards start with a C note. 

Finally, for the more acoustic-like digital pianos which have a 76 or 88 key setup start with an A note. 

Why Do Pianos Have An 88-Key Set-Up?

Traditionally, pianos are made with 88 keys in total as they are said to give the best sound options and centre the musician so as you can have equal access to all notes on the piano when needed, this allows you to play a bigger variety of music than small key set-ups on pianos. 

We have listed the best types of key sets according to your piano playing level below. 

  • Beginners 61 keys - For people who are on a budget and just starting a digital piano with 61 keys is a great choice as this gets you used to all the main notes you will be using without the keyboard being too overwhelming. 
  • Intermediate 76 keys - If you know how to play the piano but are getting back into practice or you want a piano with better sound options than a 61 key set-up then 76 keys may be the better choice.

Types Of Digital Piano Keys

As well as digital pianos coming with a wide range of different keyboards, these keys are also different when it comes to their weight, most of the high-quality types of keyboards have a weighted design to make them feel more real like a traditional piano. 

We have listed the different types of weighted keys your digital piano might come with below.

Non-weighted (Synth) 

These types of digital pianos are often the most affordable and use a spring-loaded mechanism for their keys, the keys have a plastic feel and are not great for replicating how a real piano feels and sounds because of this. 

Overall, these types of pianos are entry-level digital pianos that are best for playing a range of music as well as fast note repetitions but are not cut out for people who want to learn to play a real piano.

Semi-weighted 

Semi-weighted keys on digital pianos are closer to acoustic piano keyboard types. These keys have more additional weights than synth keyboards but still, use the same spring-loaded mechanism as above. 

For people who want a balance between heavy and lighter keys, a semi-weighted digital piano is your best bet. 

Fully-weighted (Hammer)

Lastly, we have hammer action keyboards, these keys have little hammers underneath to mimic the feel of a real acoustic piano.

Hammer keys are best for practising on if you want a digital piano which can help you play on an acoustic one too as they help you develop finger strength and understanding of notes, make sure you get a model with an 88-key set up to learn on a traditional piano.

Types Of Digital Pianos On The Market 

Now we know all about how digital pianos work and the different keyboard setups that they come with we can get into the different types of digital pianos which are available on the market. 

According to the type of digital piano you get, this will change the number of keys available on the piano. 

Console pianos 

Console type of digital pianos are popular models if you are after a digital piano that is very similar to an acoustic in terms of looks. These pianos will come with piano pedals and weighted keys which enables you to practice your playing on a more acoustic-like piano.

The disadvantages of console pianos are the console pianos weight which makes them less portable, these kinds of pianos tend to be the most expensive on the market too. 

Upright pianos

These are similar to a console type of digital pianos and are like acoustic pianos, they are the most expensive and will often feature high-quality multi-sound speakers as well as wooden weighted hammer keys for the most realistic feel.

Slab pianos 

For people who are after portable digital pianos, slab pianos might be your best choice. These kinds of digital pianos look very much like keyboards except they come with a full 88 key setup and acoustic piano keyboard weighted keys for a more real feel. 

Due to them having no stand or base, these slab pianos can be moved around anywhere without issues making them one of the most portable pianos, they are often cheaper than upright or console models too so are perfect for people who want to gets serious about piano playing but are on a budget.

Digital grand pianos

These digital grand pianos are less common due to their high price and size but are worth it if you are after impressive sound quality due to their large speaker systems and high-quality keys. These pianos are typically made by brands such as Yamaha or Kawai. 

Digital Pianos Vs Acoustic Pianos For Playing 

Digital pianos can come with some impressive weighted key set-ups which make them very acoustic-like and natural to play on, they can also be more affordable than your standard acoustic piano, which begs the question, why would you choose an acoustic piano instead? 

We have compared both digital pianos and acoustic pianos below in terms of their feel to play and other features so as you can see which keyboard might suit you for playing on. 

Digital Pianos 

First off, let's start with digital pianos, these types of keyboards in terms of design and key set-up come in a wide range more than traditional acoustic pianos do. The sound of digital pianos in comparison to acoustic pianos has even been argued to be better performing as acoustic pianos need a fair amount of maintenance to keep the quality of their tune. 

Downfalls of playing a digital piano in comparison to an acoustic one have to be their pedal which does not replicate a real damper sound. When it comes to the keys specifically, although you can buy weighted digital pianos they do not feel the same as the hammer mechanism does on an acoustic piano.

Pros 

  • Portable options. 
  • High-quality sounds with little maintenance. 
  • Wide range of key options. 

Cons 

  • Keys don't feel the same despite weighted options. 
  • Pedals are not realistic. 

Acoustic Pianos 

In comparison to digital pianos, acoustic piano types are the best when it comes to key sensitivity thanks to their hammer action behind each one, this makes two notes never the same giving the piano more dynamic range. Due to how acoustic pianos are made they have a more natural sound too. 

Negatives of acoustic pianos in comparison to digital models have to be their high maintenance and lack of portability, keys are often harder to fix and they lack electric features which can help your produce unique music.  

Pros 

  • Best for natural sound. 
  • Great key sensitivity. 
  • Dynamic range.

Cons

  • Harder to maintain. 
  • Lack of electronic functions. 
  • Not portable.

Conclusion - Is a Digital Piano Or an Acoustic Piano Better For Playing?

Overall, in terms of keys and how they feel, we would have to say a traditional acoustic piano is your best option as these types of pianos have a weighted hammer mechanism and excellent touch sensitivity which makes playing a better experience. 

If your after a more customised key set-up and don't want the extra weight then you might opt for a digital piano in this case.

Digital Pianos Vs Keyboards For Playing 

Now we have compared the keys and general specs of a digital and acoustic piano, we should also take time to note the differences between a keyboard and digital piano since they are so closely related. 

Digital Pianos 

Digital pianos will always have the upper hand over a keyboard when it comes to how they feel to play, this is because these pianos typically have weighted keys and 88-key set-ups which makes them more like an acoustic piano. 

These types of pianos have better additions such as pedals and sample sound quality too which makes them even more enjoyable to play. 

Some drawbacks of playing with digital pianos in comparison to keyboards have to be their heavier weight which makes them less portable and higher price due to their better feel and sound.

Pros

  • Better key sensitivity and feel. 
  • Higher sound quality.
  • Comes with pedals and full 88-keys.

Cons 

  • Not as portable. 
  • Higher in price.

Keyboards 

Professional keyboards on the other hand rarely come with weighted keys and have synth technology instead which make them less acoustic-like to play with. They usually only come with a limited 66-key instrument or 72-key instrument set-ups too, not the full 88. 

Keyboards do have the advantages of being lightweight however and great for beginners who are getting to grips with piano playing on a budget. For sound effects and sound customisation, you may find these devices are better too. 

Pros 

  • Customised sound options. 
  • More affordable. 
  • Portable.
  • Good for beginners. 

Cons 

  • Not acoustic-like for playing. 
  • Fake feel. 
  • Limited key setup.

Conclusion - Is a Digital Piano Or a Keyboard Better For Playing?

Overall, a digital piano is hands down the best option if you are looking for the best piano to play with in comparison to a keyboard because of its better-weighted keys and full acoustic piano keyboard set-up. 

We would only suggest choosing a keyboard instead of a digital piano for playing if you are on a budget or you are interested in more sound effects than actual instrument sound.
