A keyboard differs from a piano primarily in its keyboard and purpose: a piano has 88 heavy hammer-action keys and one, highly accurate piano sound, while a keyboard is a lightweight electronic instrument, typically with 61 lightweight keys, hundreds of sounds, and automatic accompaniment. The piano is used for teaching and mastering classical piano technique, and the keyboard is used for playing with sound, arranging and entertainment.
To sum it up
- Keyboard: The piano has 88 keys with resistance like a grand piano; the keyboard usually has 61 easy keys (5 octaves).
- Sound: An acoustic piano produces sound using hammers and strings; a keyboard plays digital samples of hundreds of instruments.
- Peculiarities: The keyboard has rhythms, automatic accompaniment, and is often battery-powered; the piano is intended solely for playing.
- Dimensions: An acoustic piano typically weighs over 200 kg and requires tuning; the keyboard can be carried with one hand.
Keyboards, acoustic pianos and digital pianos are three different instruments.
When asked what the difference is between a keyboard and a piano, it's important to distinguish between three instruments, as they are often confused in stores:
- Acoustic piano – a traditional string instrument with a vertically positioned soundboard and strings; pressing a key activates a mechanism whose hammer strikes the strings;
- Digital piano – an electronic instrument that imitates a piano: it has 88 keys with hammer action (weighted) and a sound based on piano recordings, but has no strings;
- Keyboard instrument – an electronic keyboard instrument for entertainment and arrangement, with a variety of sounds, rhythms and accompaniment functions.
Thus, a digital piano occupies a middle ground: the sound is produced electronically, like on a keyboard, but it is played like on a grand piano. For a music student, it is generally a reasonable alternative to an acoustic piano, rather than a keyboard.
Keyboard: number of keys and mechanics.
A standard piano has 88 keys (more than 7 octaves). Popular keyboards have 61 keys , or 5 octaves; there are also models with 49, 76, and 88 keys. Some piano pieces simply won't fit on 61 keys because they lack the lowest and highest notes.
Even more important mechanics . In a piano, each key sets a hammer in motion, which exerts varying resistance, and the force and speed of impact determines the volume and timbre. Digital pianos reproduce this using what is called weighted hammer action keyboard . The keyboard usually has light, spring-loaded keys, like those found on electronic organs.
Beware of the term "touch sensitive"« keyboard . This simply means that the instrument responds to pressure—the louder the strike, the stronger the force. Many keyboards have this feature, and it's an important learning feature, but it's not the same as a weighted keyboard. Touch-sensitive keys can also be light.
Sound and functions
An acoustic piano sounds like a piano—the sound comes from the strings and wooden frame, and its timbre depends on its construction, playing environment, and tuning. A digital piano focuses on one task: reproducing the sound of a grand piano as accurately as possible, usually with the addition of a few additional tones (organ, strings).
A keyboard instrument is more like a miniature music studio. Typically, it offers:
- Hundreds of sounds – piano, guitars, strings, wind instruments, drums, synthesizers;
- ready-made rhythms and musical styles;
- Automatic tracking – just play a chord with your left hand, and the instrument will play bass and drums;
- Built-in speakers, headphone output, often USB port and battery power.
Keyboard vs. Piano Comparison Chart
| Characteristic | Keyboard | Acoustic piano | Digital piano |
|---|---|---|---|
| Number of keys | Most often 61 (also 49, 76, 88) | 88 | Usually 88 |
| Mechanics | Light keys, often dynamic | A hammer striking the strings | Weighted, simulates the action of a hammer. |
| Sound source | Digital samples, speakers | Strings and soundboard | Piano samples, speakers |
| Number of sounds | Hundreds | One | From several to several dozen |
| Accompaniment and rhythms | Yes | NO | Usually none or to a limited extent. |
| Weight | A few kilograms | Usually more than 200 kg | From a dozen to several dozen kilograms |
| Headphones | Yes | No (except for models with a soundproofing system). | Yes |
| Setting up | Doesn't require | Regular, from the tuner | Doesn't require |
Maintenance and space of the house
An acoustic piano is a piece of furniture that will last for many years. Typical models weigh over 200 kg, so transporting them will require a team. The instrument requires regular tuning Manufacturers like Kawai recommend tuning it at least twice a year, and more often if you play intensively. Pianos are also sensitive to temperature and humidity fluctuations, so avoid placing them near a radiator or window.
Keyboards and digital pianos require no tuning. The keyboard fits in a closet, and headphones allow you to practice in the evening without disturbing the neighbors.
Keyboards or piano – which one to choose for learning?
- Music school or classical piano lessons: An acoustic piano or a digital piano with 88 weighted keys. A light keyboard can make it difficult to develop finger strength and dynamic control, and the transition to a school instrument can be challenging.
- For a child who is just testing whether music captivates him, A keyboard with a dynamic keycap and full-sized keys would be a reasonable starting point.
- Entertainment game, songs, group, recording: keyboards – thanks to sounds, rhythms and accompaniment.
- Small apartment in an apartment building: digital piano or synthesizer with headphones.
- Before purchasing, it is worth checking with the teacher, What tool is needed for the curriculum?.
Frequently Asked Questions (FAQ)
Is it possible to learn to play the piano using a synthesizer?
The basics, yes: notes, chords, hand coordination. For classical piano technique, the keyboard alone is not enough, as it typically has fewer keys and a light keyboard without hammer action.
What is the difference between a digital piano and a synthesizer?
A digital piano typically has 88 weighted keys and is designed to accurately reproduce the sound of a piano. A keyboard typically has 61 backlit keys, hundreds of sounds, rhythms, and automatic accompaniment.
How many keys does a keyboard have and how many does a piano have?
A standard piano has 88 keys. Keyboards most often have 61 keys, but models with 49, 76, and 88 keys are also available.
What is a dynamic keyboard?
This keyboard is pressure-sensitive: the harder you press a key, the louder the sound. However, this doesn't mean the keys are weighted—they can remain light.
Is a keyboard a synthesizer?
Not quite. A keyboard plays pre-set sounds and accompaniment, while a synthesizer is primarily used to create and modify your own sound timbres. However, in everyday speech, these terms are sometimes used interchangeably.
