+The **Concertina** is a free-reed [Musical Instrument](/wiki/Musical_Instrument) of the aerophone family, patented by Sir Charles Wheatstone. It is held between the hands and played by pushing and pulling bellows, while pressing buttons or keys to produce sound, much like an [Accordion](/wiki/Accordion).
