Schwyzerörgeli

The early makers including Eichhorn (Schwyz) and Nussbaumer (Bachenbülach) experimented with different arrangements and numbers of buttons.

The basses progress in 4ths like the Stradella system seen on chromatic and piano accordions, but in the opposite direction.

The only other variety still being made in substantial numbers today is the Schwyzerörgeli with chromatic fingering, usually with a C system (C-Griff) treble side and Stradella bass fingering, including the Minor Chords to allow for the possibility of playing Tango Music if a Bandoneon Player is unavailable.

The Örgeli with 2 sets of treble reeds of the same octave, tuned slightly apart (tremolo or 'wet'), is called a Wienerörgeli (Viennese Örgeli) because of the 'Viennese' tuning (Wienerton) which is widespread among button accordions around the world such as those made by Hohner and the Steirische Harmonika.

The internal construction (RH reed blocks) of this Örgeli also is not like the others but more like other accordions, but the fingering and the appearance is of the typical Schwyzerörgeli.
