text: A double bass is usually strung with four heavy strings pitched E 1 –A 1 –D–G; a fifth string is occasionally added—in jazz band basses, at the top of the register to allow high notes to be played more easily; in symphony orchestra basses, below the E string, tuned to C. Many basses, rather than having a fifth string, have a mechanical device with levers that increases the length of the fourth string.
