Key Differences

The bandoneon is closely associated with tango music, known for its deep, melancholic sound which complements the dance's emotional intensity. Whereas the accordion, with its brighter and more versatile tones, is used in a variety of music genres ranging from folk to rock.
Bandoneons are bisonoric, meaning they produce different notes when the bellows are pushed and pulled. On the other hand, most accordions are unisonoric, producing the same note regardless of the direction of the bellows.
Typically, bandoneons do not have the range of keys seen on accordions. While an accordion usually includes piano or button keys that facilitate playing a wide range of notes and chords.
The playing technique for bandoneons involves intricate finger coordination and control over the bellows to manage its dynamic sound. Meanwhile, accordions are generally considered easier to learn due to their more straightforward keyboard and consistent sound production.
In terms of construction, bandoneons often have a more compact, square shape, focusing on the essentials needed for tango music. Accordion, however, comes in various sizes and styles, sometimes featuring additional registers that allow the musician to change the timbre of the instrument.
