The drejelire is a string instrument with a keyboard, specifically, a type of hurdy-gurdy that uses a rosined wheel to create sound.
The drejelire is made of wood. There is a crank at the bottom, which must be moved continuously to produce sounds, and "key-like" buttons on the side, which the player must press to obtain a correct pitch.
History
The drejelire is a national instrument of Sweden, alongside the nyckelharpa.
