Bandonion

System: Birken (similiar to Janko), 152 tones
(unisonoric, logical)

(kein Bestandteil der Collection Oriwohl)

Manufacture: Klaus Gutjahr (Berlin) 2011

This bandonion follows the approach of C. P├ęguri (1925) to develop an unisonoric bandonion from an already existing bisonoric model in order to avoid a more complex new construction.

The Birken system consists of vertical whole tone rows according to the Janko principle. This results in a much more comfortable playability and advantages for bound playing.
