Bandoneon

musical instrument

The bandoneon is an offshoot of a family of german button and bellows instruments called koncertinas, invented around 1845. Koncertinas (distinct from those played in the british isles) were small square instruments which had 14 buttons on each side. Later the number of buttons increased to more than 70.

The first bandoneon was in fact a koncertina made around the year 1856 and to which the commercial name of "bandoneon" was given in memory of Heinrich Band, who had a music shop in Krefeld (north Germany). The bandoneon was developed throughout Germany under various sizes and systems. One of these many different models, the "Reinlander"(from the Rein district) was exported to Argentina at the very end of last century.

The bandoneon was very quickly adopted in Buenos Aires and became the symbol of Tango. It was never built there. Most bandoneons were made by the German maker Alfred Arnold from 1911 untill few years after the war.

The Argentinian bandoneon is a two voice instrument (each note being doubled at the superior octave) with 71 buttons. Each button plays a different note depending on whether the bellows is opened or closed (unproperly called diatonic). Around 1925, Charles Peguri, an Italian accordion player and repairer settled in Paris designed a new keyboard where each button produced the same note regardless of whether the bellows was open or closed (called "chromatic") which has been widely used in France. For playing Tango, the bandoneon must be tuned without vibrato (the two voices being precisely an octave apart).
