Description of the accordion
Accordion consists of three main parts.
- the right part of the body (1),
- the folded bellows connecting these parts (2),
- and left part of the body (3).
A griff is attached to the right side of the body with the right keyboard located on it and a strap. The number of keys of an ordinary button accordion on the right keyboard is 52.
However, there are instruments with 37 or 49 keys or more.
On the left side of the accordion there is a left keyboard. There are usually 96 keys on the left keyboard.
Less common accordions have 60, 80 and 120 keys. A strap for the left hand is attached to the left side of the accordion. On the right and left sides of the body there are gratings covering the valves.
Quality of the accordion
It is recommended to practice on the accordion with a clean tuning of the voices.
A working accordion must meet the following requirements:
Bellows with the body of the accordion must not allow air to pass through in closed position.
When you press a key in the weakest movement of the instrument, a good accordion immediately produces a sound (responses).
The keys /buttons of the keyboards must not be too tight or weak. The right keyboard must sound brighter than left, otherwise it is difficult to play a melody without drowning it out with accompaniment played on the left keyboard.
Accordion should be stored in a case at constant room temperature. Remove the instrument from the case very carefully to not to break the keys on the left keyboard and not to damage the bellows with straps.
It is necessary to protect the instrument from moisture, otherwise, the wooden parts may swell and the voices of the steel plates may rust. Then the accordion will become bad tuned, and if the keys are wooden then they will start to stuck.
