(English) Duet Concertina

System: Maccann (1884), 90 tones (unisonoric, logical)

(Collection Oriwohl, Nr. A-93)

Manufacture: Charles Wheatstone & Co (London)

From the very beginning, Charles Wheatstone and other British manufacturers built unisonoric instruments with chromatic tones, which favoured logically structured keyboard systems.

Charles Wheatstone from London built such instruments from 1830 onwards, which he called the Concertina in order to express its claim to be a concert instrument. Some virtuosos made the English Concertina very popular in the concert music of the bourgeoisie and middle classes, what was not the case with the bisonoric German sister instrument.
