The design of a keyboard and synthesizer vary significantly from each other. As mentioned earlier, the keyboard is a separate instrument that can be used for solo music composition as well as for beginner learning purposes. If you are not skilled in the field and want to improve your skills, this is our ultimate recommendation to you.

In design, it resembles an acoustic piano and is generally incorporated with an electronic circuit. The whole process works by the generation of the signals that lead to the formation of the sound when you press a key. Furthermore, keyboards are integrated with multiple keys, which produce different signals and contribute to the generation of varying sounds in the process.

In contrast, a synthesizer is not an instrument but a major component of a keyboard or a piano and is also known as the collection of sounds. There are multiple types of synthesizers available in the market, as discussed earlier, and can be used to generate new sounds or make changes in the already existing sounds. They are complex in structure as compared to the keyboards and are also incorporated with LCD screens that can be used for displaying various sounds.


The price is another factor that varies greatly among keyboards and synthesizers. Synthesizers are extremely expensive in nature and can cost you a lot even if you purchase a low-end product. On average, the most inexpensive synthesizers are available in the market at the price of around $1200, which might not be affordable by the majority of consumers.

In comparison, keyboards are budget-friendly and thus can be purchased at an extremely reasonable price around the market. There are expensive models as well that can cost somewhere around the price of their previously mentioned counterparts. However, the affordable options range from $25 to $40.


Next up on the list is the sound. Synthesizers do not contain built-in speakers, and thus, the sound is directly transmitted to the headphones while using these products. The majority of the analog synths available in the market feature built-in sounds and can be used for modification and mixing purposes. They offer enhanced precision and accuracy and thus, are perfect for both studio and stage use.

Another prominent attribute of these models is their ability to work without any external device. Keyboards, on the other hand, are integrated with built-in speakers and are more beneficial for learning purposes or composing solo music. They are not recommended for mixing and matching because of their limited abilities. Furthermore, they lack built-in sounds and thus, are dependent on external devices for this purpose.


Synthesizers also take the crown when it comes to control. They feature multiple controlling systems and are also known as control agents. The function of a synthesizer is to modify or alter a new sound or an already existing sound. For this purpose, they utilize oscillators and envelope controls which are famous built-in components of a synth.

Moreover, built-in feature effects like delay, distortion, and chorus are also utilized by some models for diversity. On the other hand, the controls of a keyboard vary from model to model. While some are available in the form of multiple controls like sliders and knobs etc., others are only integrated with keys that are the only source of sound generation.

Keyboard v/s Synthesizer: Which is Better?

Both keyboards and synthesizers have been discussed earlier in detail, along with their major differences in terms of sound, controls, price, brands as well as various applications. The choice about which is better usually depends on the consumer’s preferences. If you are looking for a product for learning purposes, we recommend going for a keyboard as it can produce multiple sounds and can help you analyze different sounds.
