Button accordion vs keyboard

According to the Cambridge dictionary, an accordion is a box-shaped musical instrument. It consists of folded/creased central part with a keyboard.

A typical accordion consists of two wooden boxes with bellows in the middle. It also has reeds/steel strips on the right-hand (treble) side. On the left-hand side are buttons in a row. The left hand side arrangement is different in different accordions. The vibration of reeds produces sound. The bass chord or note depends on the direction of movement of bellows. (The note sound changes as the direction of movement changes). Some free-reed, electronic chromatic button accordions are also available.

Accordions vary from each other in different aspects. They have different shapes and designs. The arrangement, type, and rows of buttons, number of chords, type of keyboard, and material are also different.

Out of many types of accordion, the difference between button accordion and keyboard has always been a topic of discussion. The differences can be discussed in the following aspects.

Identifying features of Button accordion vs keyboard models

Reeds, buttons, and bellows are present in both types of accordions. The main difference lies in the right-hand manual. The button accordion has rows of buttons on the treble (right-hand) side that are chromatically arranged.

While piano-style keys are present on the treble ( right-hand) side of the piano accordion.

Historically, accordions can be related to Hohner. Hohner was a thrilling band that played Irish, traditional and Celtic music.

Button accordion history

The pioneer of the button accordion is Cyril Demian. He invented this accordion in 1829 in Berlin. In the beginning, it had only five buttons/10 chords.

Piano accordion history

Bouton of Paris designed a piano accordion in 1852. Due to its popularity, this accordion gave a tough competition to its button counterpart.

Easier to play

The ease of learning and playing depends on the interest and comfort of people. Button accordion is tough to learn and is easier to play. In this accordion, buttons are wide apart and uniformly arranged on the keyboard. This layout reduces or eliminates the risk of mistakes.

The piano accordion is the first choice of most learners as it is easier to learn and play. But the buttons are closer together, and a player can mistakenly press the wrong key. Thus, while playing music with the accordion of this layout, the pianist must be very accurate and precise.

Key design

Each key produces two notes in a button accordion. There is one key per note in a piano accordion. An accordionist plays the button associated with a certain note. Button accordions also have some non-functional buttons. These extra buttons are for cosmetic purposes only. Yet, each and every key on a piano keyboard is functional.


The size of an accordion depends on the number of keys. Button accordion has a compact size. The small-sized manual on this accordion makes it handy and easier to carry. This feature also makes it easier to play.

The piano accordion, on the other hand, has large and protruding keys. These factors make it heavier as compared to the button accordion.

Number of notes

A piano has a maximum of forty-five notes. There can be a maximum range of sixty-four notes on

the right-hand side of the button accordion.


The button accordion has more range as compared to the other one. Generally, it has 5 rows of buttons. It is uncomfortable for small players to extend all notes in the piano accordion due to its large size. But young players find it challenging to reach farther on the keyboard.

The more frequent use of the thumb, however, reduces this discomfort. Because button accordions are compact, playing all keys is easier for players.

Fingering style

In a conflicting talk of button accordion vs. piano, fingering style has a remarkable significance. There are more fingering options in a button accordion than the piano accordion. Buttons in this accordion are small and closely arranged. But it requires twisting of the wrist and fingers. Two different chords can be played by using the same fingering pattern.

Keys in a piano accordion are wide apart that allows better reach. Parallel keys in this accordion allow relaxed wrist and fingers position. While approaching farther keys, the music player has to stretch a little bit. To play a certain chord accordionist employs the same technique as used by a pianist.

Bass systems

The bass system holds crucial importance while floating in the discussion of differences between these accordions. Button accordion has Stradella system and French 3-3 bass system. You can get a free bass system in this type of accordion too. This accordion has 12, 48, 72, 96, or 120 basses. The button accordion has up to 3+ octaves.

A Piano accordion is also available with a stradella or free bass system. Convertor bass system accordion is also available. It has approximately 120 bass buttons. A piano accordion has around 4+ octaves.

Trans positioning

Since button accordions have duplicate rows, it allows the player to use the same fingering pattern. Buttons are closer and easy to find in this accordion. Thus, a player can easily transpose from a lower note to a higher one.

Transposing is difficult in piano accordion because buttons are far apart. It is not convenient to play transitions from low notes to high notes. Trans position becomes demanding when the singer cannot perform on a specific range.


While discussing the characteristics of the button accordion and piano, legato has a remarkable role. Just like a piano, large keys of piano accordion impart large surface area. It enables the player to hold on to one note for a few seconds. It allows for a smooth rhythm to the music.

Buttons in the button accordion are small and difficult to find. It compels the player to let go of different notes while finding them. Legato becomes easier in these accordions when an accordion player learns to use duplicate rows.


Barring is the ability to play multiple notes simultaneously with one finger. Barring is easier to learn in button accordions due to their close-packed position. An accordionist can hold on to more than one key at the same time. This is possible due to the small-sized keys in these accordions.

It would be difficult in piano accordion due to its large-sized keys. A player cannot press multiple keys with the same finger at once.
