Accordion bellows old

Old accordion bellows: discover the structure that brings life to this iconic instrument, from its handcrafted construction to its role in global folk music.

About this subject

The bellows of an accordion are the instrument's heart, generating the airflow that vibrates metal reeds. Traditionally built from layers of cardboard, fabric, and leather, the bellows must be fully sealed to prevent air loss and ensure quick response to the musician's touch. A typical accordion has 16 to 20 folds that allow expansion and compression, creating dynamics from whisper to fortissimo. Bellow design directly affects the instrument's weight: older models, such as those made in early 20th-century Italy and Germany, often had sturdier bellows with metal reinforcements, making them heavy but durable. In global folk music, the accordion appears in traditions ranging from French musette to Argentine tango and Brazilian forró. Maintenance of bellows is a specialized craft: artisans repair them by replacing cardboard or re-gluing corners with fish glue, a technique from the 19th century. Well-maintained bellows can last over fifty years, and many vintage instruments still perform at festivals and recording sessions.
