Accordion Parts

he accordion is a wind instrument made up of a bellows that opens and closes, two wooden harmonic boxes and a fingerboard. The sound in these instruments is produced when opening and closing the bellows, therefore it does not need to be blown by the person as it happens with other wind instruments.


The sound is produced by the combination of all its parts, it has a mechanism that when it opens or closes lets air pass through its entire structure until it reaches the reeds, these in combination with the keys generate the sound.

Accordion Parts


Also called a fan . It is the very wide space that remains in the middle of the accordion, through which the air becomes forced by vibrating the metal reeds inside. This is manipulated by the accordionist to control the sound quality and volume.

When the bellows closes it blows and when it opens it sucks air. This air entering or leaving produces the vibration in the reeds, thus creating the sound.

Leather chamois

Its function is to prevent air from passing to the tongue, which must not vibrate.


This part can only be seen on large accordions, which help the accordionist to handle the weight of this musical instrument, where the shoulder strap is placed as a counterweight. This strap is generally made on the basis of leather. It allows the artist to stand with the accordion while playing.

Accordions often have straps that close the instrument when not in use, and at the same time have straps that keep the left hand in place.

Tether straps

These are used to perform air movements, either opening or closing the accordion.


This is the point that anchors the reed to the still side of the accordion.



Also called a fingering board . Piece of wood that has 31 buttons with different functions, which offer two notes, one closing and the other opening.


Place where the windows are, which is shown as a hole where the set of tabs is placed.

Manual systems

These systems are located where the left and right hands are placed. In the system directed to the right hand there is a keyboard or a series of buttons that when touched produce the melody. On the other hand, the system on the left has a set of buttons that maintain an order either by chord, by individual notes, or by groups of five, with which the melody is produced.


It is a metal structure that is used as protection for the sound mechanism.

Air valve

It is one that is responsible for absorbing the wind. When the accordion is winged and pressed, the amount of air required to perform a certain performance is achieved.


It is the part of the accordion that contains the bellows, which is enclosed in two wooden boxes. In these boxes are the reed chambers. Its sides are covered with a metal grille, which is decorated and at the same time allows air flow.

Bass board

Board with 12 buttons corresponding to the fingerboard row.

Paddle Mechanisms

This is the part of the accordion that has the function of controlling the air current, prohibiting or allowing certain whistles or reeds to vibrate. With these mechanisms the accordionist will be able to control the chords and the notes he plays.


Part that gets to adapt to the accordion to avoid discomfort with the friction of the bellows.


Here various buttons are shown, where each represents a harmonica, where pressing it uncovers it at the same time that the air coming from the bellows gives rise to the vibration of the harmonica. The tones can be changed on a key located above the buttons.
