Around 1836 a second row was added on both sides to the Deutsche Konzertina. On the right-hand side (fig.), this row added 5 additional tones to the tone stock (black), which were not yet included in series 1. Three tones of the new G-Major series (arrows) become repeat tones (red), as they are already present in series 1 for the other bellows direction and can now be played (with several keys) on push and pull. Both major series still follow here an identical structure, but this cannot be continued in later extensions. The arrangement then follows the best grip or simply the still usable area on the housing.
