bassist

n. singer with deep bass range voice; musician who plays a bass instrument

A bass player (bassist) is a musician who plays a double bass or electric bass (also referred to as bass guitar). Certain musical genres tend to be associated with each of these instruments. Since the 1960s, the electric bass is the standard bass instrument for rock and roll, jazz fusion (and occasionally other forms of jazz), heavy metal, country, reggae and pop music. The double bass is the standard bass instrument for classical music, Bluegrass, and Swing-era and Bebop-era jazz music. However, there are exceptions in both cases. Some 1990s and 2000s rock, pop, and punk rock/psychobilly bands use a double bass, such as Barenaked Ladies, Two Tons of Steel, Tiger Army, The Living End, HorrorPops occasionally. Some composers of modern art music use the electric bass in a chamber music setting, and some jazz big bands use electric bass.
