Upright Bass

n jazz, blues, rockabilly and other genres outside of classical music, this instrument is commonly called the upright bass, standup bass or acoustic bass to distinguish it from the (usually electric) bass guitar. In folk and bluegrass music, the instrument is also referred to as a "bass fiddle" or "bass violin" (or more rarely as "doghouse bass" or "bull fiddle"[8]). While not a member of the violin-family of instruments, the construction of the upright bass is quite different from that of the acoustic bass guitar, as the latter is a derivative of the electric bass guitar, and usually built like a larger and sturdier variant of a viola de gamba, its ancestor.
