How Does an Accordion Work: A Beginner’s Guide to Understanding the Mechanics

The accordion is a unique musical instrument that has been around for centuries. It is a portable instrument that is played by compressing or expanding the bellows while pressing buttons or keys. The accordion produces sound when air flows across strips of brass or steel called reeds, which vibrate inside the body of the instrument.
At first glance, the accordion may look like a complicated instrument, but it is actually quite simple in design. It has three main components: the right-hand side, a piano or button keyboard, the bellows, which act like a bow, and the left-hand side, which has 120 buttons. To produce sound, the basic motion is to “pull and press,” as explained by Latvian-born accordionist, Ksenija Sidorova.
In this article, we will explore how the accordion works, including its history, components, and how it produces sound. We will also discuss the different types of accordions and their unique features. Whether you are an accordion player or simply curious about this fascinating instrument, this article will provide you with a better understanding of how the accordion works.
Basics of an Accordion
An accordion is a musical instrument that produces sound by compressing and expanding its bellows while pressing its keys or buttons. It is a portable and versatile instrument that is popular in many musical genres, including folk, jazz, and classical music.
Parts of an Accordion
An accordion has three main components: the right-hand side, the left-hand side, and the bellows.
Right-hand side
The right-hand side of the accordion features a keyboard, which can be either a piano or a button keyboard. The keys or buttons on this side of the instrument are used to play melodies and harmonies.
Left-hand side
The left-hand side of the accordion features bass and chord buttons. These buttons are used to play accompaniment and rhythm parts.
Bellows
The bellows of the accordion are made of pleated layers of cloth and cardboard. They are used to compress and expand air, which produces sound when the keys or buttons are played.
Accordion Types
There are two main types of accordions: piano accordions and button accordions.
Piano Accordions
Piano accordions have a piano-style keyboard on the right-hand side and bass and chord buttons on the left-hand side. They are popular in many musical genres, including classical, folk, and jazz music.
Button Accordions
Button accordions, also known as diatonic accordions, have buttons on both the right-hand and left-hand sides of the instrument. They are popular in many folk music traditions, including Cajun, Irish, and Mexican music.

How Sound Is Produced
The accordion is a free-reed instrument that produces sound when air flows over the reeds. The bellows, which is the part of the accordion that is squeezed and expanded, forces air through the reeds. The reeds, which are made of brass or steel, vibrate to produce sound inside the body of the accordion.
Bellows
The bellows of the accordion are made of pleated cloth and cardboard, and are responsible for pushing air through the reeds. When the bellows are compressed, air is forced through the reeds and when the bellows are expanded, air is sucked back in. This movement of air creates a vacuum that causes the reeds to vibrate.
Reeds
The reeds are the heart of the accordion and are responsible for producing the sound. They are made of metal and are mounted on reed blocks inside the accordion. The reeds are tuned to produce specific notes when air flows over them. There are two types of reeds in an accordion: the treble reeds and the bass reeds.
The treble reeds are mounted on a plate and are controlled by the buttons or keys on the right-hand side of the accordion. When a button or key is pressed, a valve opens, allowing air to flow over the reeds and produce sound. The treble reeds are arranged in pairs, with one reed in each pair sounding when the bellows are compressed and the other sounding when the bellows are expanded.
The bass reeds are mounted on a separate plate and are controlled by the buttons or keys on the left-hand side of the accordion. The bass reeds produce a single note when a button or key is pressed. The bass reeds are arranged in groups, with each group producing a different chord sound.
the accordion produces sound when air is forced through the reeds by the bellows. The reeds vibrate to produce sound, and the buttons or keys on the accordion control which reeds are activated and which notes are produced.
Playing the Accordion
Playing the accordion involves using both hands to create music. The right hand plays the keyboard side, while the left hand plays the bass side.
Keyboard Side
The keyboard side of the accordion contains the treble notes. It is played by pressing the keys or buttons on the right-hand side of the accordion while simultaneously moving the bellows in and out. The keys are arranged in a similar pattern to a piano, with white keys representing natural notes and black keys representing sharps and flats.
To play a note, press the key or button and then move the bellows in the appropriate direction. The harder you press the key or button, the louder the note will be. The speed at which you move the bellows also affects the dynamics of the sound.
Bass Side
The bass side of the accordion contains the bass notes and chords. It is played by pressing the buttons on the left-hand side of the accordion while simultaneously moving the bellows in and out. The buttons are arranged in rows and columns, with each button producing a different bass note or chord.
To play a bass note, press the button corresponding to the desired note and then move the bellows in the appropriate direction. To play a chord, press multiple buttons at once. The bass side also contains a button for the air release, which is used to silence the bass notes and chords.
Playing the accordion requires coordination between the hands and the ability to read sheet music or play by ear. With practice, you can learn to create beautiful music on this unique and versatile instrument.
Maintenance and Care
Taking care of your accordion is important to ensure that it lasts for a long time and performs well. Here are some tips to help you maintain and care for your accordion:

Frequently Asked Questions
If you’re new to the accordion, you probably have a few questions about how it works. Here are some of the most frequently asked questions:
How does an accordion produce sound?
An accordion produces sound through a combination of the bellows and the reeds. When you compress or expand the bellows, air flows across the reeds, causing them to vibrate and produce sound. The right-hand side of the accordion typically has a keyboard that allows you to play melodies, while the left-hand side has buttons that allow you to play chords and bass notes.
How do you play the accordion?
Playing the accordion requires coordination between your left and right hands. The right hand plays the melody on the keyboard, while the left hand plays chords and bass notes on the buttons. To play the accordion, you need to use the bellows to produce sound, while using your hands to play the appropriate notes and chords.
How do you tune an accordion?
Tuning an accordion can be a complex process that requires specialized tools and knowledge. The reeds inside the accordion need to be adjusted to ensure that they are producing the correct pitch. This is typically done by a professional accordion tuner, who will use a tuning meter to adjust the reeds as needed.
What are the different types of accordions?
There are many different types of accordions, each with its own unique features and characteristics. Some of the most common types include piano accordions, button accordions, diatonic accordions, and chromatic accordions.
