The accordion is a free-reed musical instrument of the bellows-blown type, often played with both hands. Accordions are often used in various genres of music, including polka, Cajun, zydeco, Tex-Mex, and folk music. To play the accordion, the player holds the instrument in front of them and squeezes the bellows while pressing buttons or keys to play different notes.
Accordions come in a variety of sizes and shapes, from small, one-row models to large, multi-row models. The most common type of accordion is the piano accordion, which has a keyboard on one side and buttons on the other. Other types of accordions include the button accordion, which has buttons on both sides, and the melodeon, which has a keyboard on one side and a row of buttons on the other.
