Harmony flute
bisonoric
(Collection Oriwohl, Nr. 309)
Manufacture: Co. Busson around 1850
After the concertina and bandonion, this harmony flute marks the beginning of the accordion section of the tour. The decisive criterion is the presence of prefabricated chords (ready-made chords) that can be played with one key.
At the beginning of the tour, a Busson harmony flute was presented that only has a melody side but no chords. In contrast, the left instrument can be used to play some chords with the left hand.
A follow-up instrument to the Demian accordion, which has like this a number of chords and follows the bisonoric principle.
In contrast it is not equipped with button keys and the mechanics are outside the case. (The white keys are a later repair).
