The double bass is a big stringed instrument. It is also called the contrabass, dubass or upright bass. It is used in orchestras, jazz bands, rockabilly bands, bluegrass music, and some country music bands. It plays low-pitched musical notes in musical ensembles and bands. In jazz bands, these low-pitched musical lines are called the "bass note." The double bass looks like smaller instruments like the violin, viola, and cello.
