Akkordolia
The akkordolia is a stringed musical instrument that hails for Austria and Germany. The strings of this instrument are made of metal steel and are pressed down using a keyboard that is similar to that of a typewriter.
Akkordolias were built up until 1939. Distributors went over the countryside selling those instruments to people who had no education or little musical knowledge. The advertising was, “Inside one hour you can make music!” The buttons had numbers and a tablature was used to show the melody.
