About the double bass
The double bass, also known as the upright bass, the acoustic bass, the bull fiddle, the bass fiddle, the string bass, the contrabass, or simply the bass, is the largest and lowest-pitched chordophone in the modern symphony orchestra (excluding rare additions such as the octobass). It has four or five strings, and its construction is in between that of the gamba (viol) and the violin family.
The bass is a standard member of the orchestra's string section, along with violins, violas, and cellos, as well as the concert band, and is featured in concertos, solo, and chamber music in Western classical music. The bass is used in a range of other genres, such as jazz, blues, rock and roll, rockabilly, country music, bluegrass, tango, folk music and certain types of film and video game soundtracks.
The instrument's exact lineage is still a matter of some debate, with scholars divided on whether the bass is derived from the viol or the violin family.
