A combination of an upright (or double) bass and an electric guitar. Similar to percussion, the bass guitar is used in almost every type of music in common circulation (the exception being, of course, percussion ensembles). Tuned one octave lower than an average electric guitar, the bass guitar is very easy to pick up and attain instant results, but very hard to master. Prominent styles on the bass guitar include slapping, tapping, and plucking.
