Accord-Harmonium

System: Piano, Kanzellenakkorde

(Collection Oriwohl, Nr. B-59),  Das Instrument im Film

Manufacture: Co. Glass (Berlin, founded 1928) after 1928
(Zinc reedplates with brass reeds; H: 90cm, B: 63cm, D: 40cm)

Before 1800, reeds were first installed in organs
(with pipes) as supplementary voices. This led to the development of the harmonium.

Of these, the Accord-Harmonium is a special case because of its ready chords taken over from the accordion. It consists of a keyboard of two octaves (c-c2), as well as 8 basic basses (left row of buttons) plus chords.

The functionality corresponds to an accordion as it shows in the name.
