What is Piano?

The piano is a keyboard musical instrument with rows of black and white keys. These keys, when pressed, strike strings inside the keyboard with a hammer to produce vibrations and sound. Each key is attributed to a different note. There are two main types of modern piano: the grand piano and the upright piano. 

Each key on a modern piano is affixed to felt-covered hammers to produce the finest quality of sound. The cast-iron frame of pianos allows them to withstand the tension of the strings as well as produce sounds louder than their older counterparts. Other parts include pedals, which are used for different purposes. 

Pianos have the widest range of notes on any musical instrument, as it covers more than seven octaves. These extremities in the notes of a piano allow pianists to choose and play from a wide range of genres of music, including but not limited to classical, popular, and jazz. 

The modern piano was invented around the year 1700 AD, by Italian inventor Bartolomeo Cristofori. It was named ‘pianoforte’ since it could be both soft (piano) and loud (forte). Although the piano is not the first string instrument, it is easily one of the most popular and widespread. 

What is Casio?

Casio Computer Company, Limited is a Japanese world-renowned company that is involved in the manufacture of a wide variety of electronic products, ranging from watches and calculators to music instruments. The electronic keyboards by Casio are so widely used that they are often simply referred to as a Casio. Casio also manufactures electronic pianos. 

Unlike pianos, Casios are not string instruments. Each key on a Casio keyboard is assigned to a sensor, and each sensor, in turn, is assigned to a musical note. The correct term for Casio keyboards would be a synthesizer, which is modeled to resemble a piano. Electronic pianos by Casio, although large and weighted, also make use of the same sensor technology to produce music. 

Since Casios are technically synthesizers with amplifiers and speakers, they come pre-loaded with a wide range of settings to choose from. The modes include different genres of music, which can be used to tune the Casio to produce music relevant to the desired genre. Other functions include an in-built recorder for musicians to record their sessions. It is also possible to upload the sounds of other instruments to the settings. Pianists can then play the recordings while they practice the piano and play in sync with the said instruments.

Main Differences Between Piano and Casio 

  1. The term ‘piano’ originated from the early versions of the modern piano, which was known as a pianoforte. Casio is the company that manufactures electronic products, one of which is the electronic keyboard, popularly called Casio. 
  2. Pianos produce sound and vibration through hammers striking strings. Casio keyboard use sensors technology to produce sound. 
  3. Modern pianos are huge and heavy, which also results in a much higher price tag. On the other hand, Casio keyboards are much smaller and can easily be seated on a table of average size, making them portable and cheaper. 
  4. Although Casio keyboards can cover a wide range of music and genres, they are more popularly used to produce commercial music. Pianos produce a much more original sound and are therefore used for almost all genres of music, with a special emphasis on classical music. 
  5. The origin of the modern piano can be dated back to around the year 1700, making them almost 280 years older than the first batch of Casio’s electronic keyboards. The Casiotone Model-101 was released in the year 1981. 


Pianos are easily one of the most popular instruments in the present and history of music. Classical music is almost incomplete without pianos. In addition to that, pianos are also widely used in other genres of music as well. 

Casio electronic keyboards, being digital in nature, can easily be pre-programmed to fit any type and genre or music in them. They can also be modeled specially to target a specific genre. Thus, owing to this versatile nature, keyboards are widely used in the production of commercial music. Most of the modern music bands have replaced pianos with electronic keyboards due to higher portability and being more suited to modern commercial productions.
