Various German concertina systems share common construction features and core keyboard layout. In the United States, particularly in the [[Midwest]] where there are many German and Central European descendants, the term ''concertina'' often refers to the [[Chemnitzer concertina]], which is bisonoric and closely related to the [[bandoneon]], but features a different keyboard layout and decorative style, including a few mechanical innovations pioneered by German-American instrument builder and inventor [[Otto Schlicht]].<ref name="Worrall2009-vol2">{{cite book|author=Dan Michael Worrall|title=The Anglo-German Concertina: A Social History|volume=2|url=https://books.google.com/books?id=JKZO1aevsiIC|date=1 January 2009|publisher=Dan Michael Worrall|isbn=978-0-9825996-1-7}}</ref>{{rp|204}} A related variant is the [[Carlsfelder concertina]] from [[C.
