Bandoneon
Pneumatic instrument, soul of tango

Pneumatic instrument, soul of tango
The sound of the bandoneon is piercing, sharp, nostalgic, with a pronounced reed “cry”. Unlike the accordion, it has a square body and a complex button system where compressing and expanding the bellows on the exact same button can produce different notes.
A square instrument with polygonal covers on the sides, featuring a huge number of mother-of-pearl buttons (up to 71–74 buttons) controlling a complex system of internal reeds.
