144 Einheits-Bandonion

How to use

This website wants to help learning the Bandoneon keyboard.
The layout is based on the 142 button version (“Rheinische Tonlage”).

To internalize the button location on the both manuals the button map can be displayed.

• The tabs above the keyboard switch the direction of the bellows (open/pull or close/push) and the side (left or right).
• Select a key and a mode to display a scale — e.g. C Major.
• Select a key and a quality to display a chord — e.g. E m7.
• Keyboard shortcuts: l, L, r, R select the side and direction; M, m, 7 select Major, Minor and Septime chord; c, d, e, f, g, a, b select the key; add # to select sharp key; C toggles button colors.

The keyboard layout is based on the Alfred Arnold 142 button Bandoneon (bisonoric, “Rheinische Tonlage”)
