Bayan

The Bayan is a special class of chromatic button accordion from Russia. The keyboard is most often B-System, and the keyboard is closer to the front of the instrument than on Western European accordions. Reeds are rectangular in shape, rather than trapezoidal, broader, and are often mounted in groups to brass plates, giving them a brighter, louder sound, and making the instrument much heavier!

Register shifts are accomplished with chin levers at the top of the treble keyboard.
