The bandoneon is an instrument of exceptional expressivity, which made it perfect for a musical genre that intends to communicate all the rainbow of possible emotions.
In addition to its great sound range -at least 142 notes (compare it with a piano which has 88), the character of its sound changes depending of the actions of opening (smooth, airy and sweet) and closing (ruff, strong and throaty).
In Anibal Troilo’s orchestra, his bandoneon is the instrument at the center of the musical arrangements.
