Digital Piano vs Acoustic Piano – The ultimate buyer’s guide-Nepal

What to Consider When Buying a Piano: Acoustic or Digital?

The first step in buying a piano is to decide between the two different types —the acoustic and the digital piano.

Many musicians find it difficult to decide between the two. Take Timmy for example. Timmy is a high school student who loves listening to the latest pop songs on Spotify. He wants to learn the piano so that he can play his favourite songs. The lady who lives across his home, Sarah, is a mother of three. She’s a working adult who wants to seriously learn the piano. Also, there’s Jason, a busy working adult in his early 30s. And there’s Stephanie, a retiree who’s thinking of picking up a new hobby. They are all facing the same dilemma—should they buy an acoustic or digital piano?

Choosing the right piano isn’t easy. You’ve got to think about the costs, the sound, maintenance, etc. Being a pianist myself, I’m fully aware of your predicament. Therefore, this article compares the different features of digital and acoustic pianos to help you make a decision. At the end, we’ll also show our recommendations for Timmy, Sarah, Jason, and Stephanie.

Acoustic piano: mechanism and types

An acoustic piano is, in a sense, as old-school as one can get. It has hammers and steel strings that are enclosed by a wooden exterior. The keys are connected to the hammers. When a key is pressed, the hammer moves and strikes the strings, causing them to vibrate and produce the sound.

There are two types of acoustic pianos: the grand piano and the upright piano. A grand piano has a frame and strings that are extended horizontally. It has a longer body and thus takes up more space. After playing the keys and releasing your fingers, gravity resets the keys and brings them back to their resting positions.

An upright piano has strings that run vertically. It’s a lot more compact than the grand piano. The upright piano often fit comfortably in houses or apartments and is thus a more convenient choice. When your fingers are released from the keys, they are reset via a spring mechanism, which is subject to wear and tear.

Inharmonicity is another factor that distinguishes the grand piano from the upright piano. Inharmonicity is the degree to which an overtone sounds higher in pitch than its primary pitch. A sound with lower inharmonicity is therefore more accurate. The grand piano has longer strings that give it not only a richer tone but also less inharmonicity. The upright piano has shorter strings and thus more inharmonicity, leading to octaves that sound less in tune. But don’t assume that the upright piano is inferior. Many other things can also determine the sound, such as the quality of the materials used and the craftsmanship.

Digital piano: mechanism and types

The digital piano is an adapted, more modern version of its acoustic counterpart. It produces sounds digitally (as its name suggests): when you press a key, the piano’s electronic speakers will play back high-quality recordings that were previously taken from acoustic pianos.

There are three types of digital pianos: the grand piano, upright piano, and portable piano. The grand piano has a higher-quality sound system and better key movements. It is, however, costlier and only offered by certain manufacturers. Like its acoustic counterpart, the upright digital piano is commonly used in homes. The digital and acoustic versions are similar in size, but the digital version weighs less. The portable piano is the lightest of the three. It comes with a stand rather than “legs.” The keys and exterior of a portable digital piano are usually made of plastic. 

Acoustic vs digital piano—which is better?

So now that we’ve understood how the digital and acoustic pianos function, let’s put them side by side.

Sound

One of the most important factors to consider is the sound of the instrument. Unsurprisingly, the acoustic piano produces a better sound. The acoustic piano, as mentioned before, produces a sound when the hammer strikes a string. It gives you an authentic, acoustic sound that has a warmer, more resonant tone. You also have better control over the articulation and expression of the musical notes. A digital piano, on the other hand, can only mimic the sound of the acoustic piano. Its sound is a digital file and thus doesn’t allow for the same acoustic nuances. Nonetheless, a high-end digital piano could sound better than a low-end acoustic piano.

Maintenance

An acoustic piano requires more maintenance. The wooden exterior, the felt on its hammers, and the steel strings are all delicate features that need proper care. Therefore, you have to be mindful of an acoustic piano’s

1. Tuning. To keep your piano in tune, it has to be tuned about 1-2 times every year. Often, you would require the assistance of a professional, which will increase your expenses.
2. Vulnerability to humidity and temperature fluctuations. Wood and felt are highly sensitive to big changes in temperature or humidity levels. If not kept under a suitable environment, the components of an acoustic piano could be affected. (Ideally, your acoustic piano should be kept in an environment of relative humidity ranging between 45% and 70% and a constant temperature of approximately 20˚C or room temperature.)

A technician can restore your piano to optimal precision in a process called regulation, which involves adjustments ranging from turning screws to sanding down wood surfaces.

Versatility – utility and portability

What the digital piano may lack in terms of sound, they make it up with some additional features. These features allow you to use the digital piano in more than one way, making it a more versatile instrument:

• Other instrument sounds: With the digital piano, you can produce the sound of almost any instruments, ranging from a saxophone to a choir. You can play around with the different types of sound, and choose the sound that suits your music best. Moreover, you can start a drum beat track and play to the beat, which will transform your keyboard into a small ensemble.
• Recording: Residing at the side of the digital piano is a port that connects the piano to your computer. This connection allows you to record and store your playing as a digital file. This is a very useful tool, especially for budding songwriters, who can manipulate their recordings with softwares.
• Volume control: The digital piano comes with a volume knob and a headphone output, allowing you to practice anywhere without disturbing others.
• Portable: Digital pianos differ in types and sizes, but they are all more portable than their acoustic counterparts. Most digital pianos can be moved by one person. Their smaller size also makes them a keyboard-instrument of choice in gigs or performances.

Touch Sensitivity

The touch and feel of playing a digital piano and an acoustic piano can be very different. One reason is the weight of the keys. Some strength is required when you strike the keys of an acoustic piano. As for digital pianos, a gentle touch on their keys could produce a sound. Many manufacturers make up for this by introducing weighted keys, which mimic the heaviness of the acoustic piano keys.

Some pianists turn away from digital pianos because of their lack of touch sensitivity. The acoustic piano is more touch-sensitive.The strength and movement of your fingers determine the tone of the sound, and you can produce different shades of sound on the same key. But on the digital piano, because the sounds produced are digital, there is a finite number of tones that can be produced. In other words, even though you played a key differently, the sound might be the same. This limitation can in turn affect the expression of your music.

Price

In general, an acoustic piano costs more than a digital piano. A low- to mid-tier upright acoustic piano could cost 3-5 lakh to above , while a digital one could be priced at anywhere from 20 thousand  onwards.

With that said, the resale value of a digital piano is much lower than that of an acoustic piano. It is difficult to gauge the resale value, which largely depends on the model and the condition of the piano. But a digital piano depreciates much quicker than an acoustic piano, because many new, more advanced models of digital pianos are released every year. Therefore, while the acoustic piano is more costly, it is a better investment in the long-run.

Pedals

An acoustic piano comes with three pedals: soft pedal, sostenuto pedal, and sustain pedal. (The sustain pedal is commonly used in all genres of music, while the soft and sostenuto pedal aren’t frequently used.) But some digital pianos come with only a sustain pedal, and some (in particular portable digital pianos) don’t come with any. Of course, you can purchase a sustain pedal separately, but the other two pedals—sostenuto and soft pedal—aren’t always available as an add-on option. It is thus important to determine whether the presence of the pedals will make a difference in your playing experience.
