What is the difference between a digital piano and an acoustic piano?

Choosing between a digital piano and an acoustic piano is a common choice for many people looking to start playing or upgrade their instrument. Both options have their advantages – but they differ in several important areas: sound, playing feel, maintenance, functionality and, last but not least, lifestyle.

The acoustic piano is a classic craft, where the sound is created naturally by hammers striking strings. This produces a dynamic, vivid sound with overtones and resonance that vary depending on the acoustics of the room and the player's touch. Digital pianos reproduce the sound through advanced technology – often in the form of high-quality samples of real grand pianos – which creates a very realistic piano sound. Especially in the premium segment, sound reproduction today is so advanced that many people have difficulty hearing the difference.

A clear advantage of digital pianos is that they are maintenance-free. They do not need tuning, are not affected by temperature or humidity, and are easy to move. An acoustic piano, on the other hand, needs to be tuned regularly – usually once or twice a year – and should be placed in a stable environment where it is protected from rapid climate changes.

When it comes to playing feel, the traditional piano still has the upper hand, thanks to its authentic mechanics. The hammer system provides a resistance and direct contact that many experienced pianists appreciate. But digital pianos have evolved enormously, with weighted keys, pressure point simulation and sometimes wooden cores in the keys – all to mimic the feel of a real piano. The best digital pianos today come very close to the acoustic playing experience.

Another important difference is the sound level. On an acoustic piano, you can play loud or soft depending on your touch – but you can’t adjust the volume. A digital piano has volume control and the ability to play with headphones, which is invaluable in an apartment or for late-night practice sessions. Digital pianos also offer modern features such as a metronome, recording, different instrument sounds and the ability to connect to apps, computers or sound systems via USB or Bluetooth – something that the acoustic piano obviously doesn’t have.

Finally, the instruments differ in size and weight. An acoustic piano is heavy, often over 200 kg, and not very easy to move. A digital piano is significantly lighter, more compact, and easy to transport, making it more practical for many homes and teaching environments.

So which one should you choose? It depends on your needs and priorities. If you are looking for a maintenance-free, technically flexible instrument with the ability to practice quietly – then a digital piano is an excellent choice. If, on the other hand, you are drawn to the traditional feel, sound and expressive power of an acoustic instrument – ​​then a real piano might be the one for you.

Regardless of which you choose, we're happy to help you find the right model based on your goals, your environment, and your musical journey.

What to consider when choosing a digital piano

Here are the most important things to have ready before you buy:

1. Game feeling / key action (Key Action)

   • Weighted keys: the keys feel heavier in the bass and lighter in the treble, similar to an acoustic piano. Provides better control and dynamics.

   • Hammer action: even closer to the feel of a real piano.

   • Touch sensitivity: keys that react differently depending on how hard you press — important for musical expressiveness.

2. Number of keys

   • 88 keys are usually standard for a full range equivalent to acoustic pianos.

   • If you are playing beginner pieces, fewer keys may be enough, but for classical repertoire and full expression, the entire range is needed.

3. Polyphony (number of notes played simultaneously)

   • The higher the polyphony, the better the piano can handle complex pieces, sustain pedal, layers of sounds, etc.

   • For beginners, 64–128 notes are often enough, but if you want more room to develop, aim for 192–256.

4. Sound quality

   • Sampled or modeled sounds that mimic the sound of concert grand pianos with multiple layers depending on the touch.

   • Speaker system: powerful and well-balanced speakers make a big difference at home. If you plan to play live, the ability to connect external speakers can be important.

5. Pedals

   • At least one sustain pedal. For more advanced playing, three pedals (sustain, soft, sostenuto) are usually good if you want to fully emulate an acoustic piano.

6. Extra features and connections

   • Built-in functions such as metronome, recording, playback, different sound choices and layers (layer/split).

   • Connectivity: USB/MIDI, Bluetooth, headphone jack. Important if you want to play silently, record, use software or connect to a sound system.

7. Size, weight and location

   • Will it be permanently on a stand, or will it be moved frequently (stage, travel)? Portable “slab” models are lighter and more agile, but may compromise on speakers and cabinet design.

   • Measure the space at home so that the instrument can fit — both width, depth and height — and that cables and pedals can be accessed.
