Atzarin Bandonion - hold, control and stability.

On an Atzarin bandonion it is the hand, not the wrist or forearm, that is in constant contact with the palm rail, enabling a firm hold on the instrument, very important for stability and tone forming via bellows control. Moreover, it is the part of the hand that we naturally use to push objects that is in contact with the instrument, the base of the palm and padded base of the thumb where the hand meets the wrist.

As the hand is raised from the end of the instrument a comfortable, natural angle of the forearm and wrist is maintained, and no part of the hand or wrist touch the fretwork, which would block the sound. The raised position of the hand on the palm rail, and the position of the palm rail in relation to the buttons, allow the hand and fingers to form a strong, relaxed, natural arch, like when you drum your fingers on the table.

The hand strap supports the joint between the back of the hand and the wrist, allowing the hand to arch naturally without restraint, whilst keeping the hand firmly in contact with the palm rail. As the strap supports the joint it eliminates play between the hand and forearm at the wrist when opening the bellows, protecting the wrist from strain.

The Atzarin bandonion's button arcs also help to improve control and stability of the instrument by greatly reducing movements that could have a negative impact on bellows control.

The need to slide the hand up and down the hand rail, as on B and C system bandonions in order to reach buttons at either end of any row, is greatly reduced by the ergonomic, curved and sloping rows of compactly spaced buttons that simply decrease the physical distance between buttons. This means that simply spreading the fingers is enough where sliding the hand would be necessary on straight rows of accordion type buttons.

The need to slide the hand back and forth, as on some concertinas and even traditional bandoneon in order to reach notes on rows further from the hand rail, is eliminated by having only three rows of buttons. The streamlined curves form a trim button arc, where buttons on any row can be reached by merely curling or extending the fingers, without needing to move the hand.
