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.
Classic bass guitar players include Paul McCartney, Victor Wooten, and Sting.
A walking, talking clarity issue. A member of a marching band (particularly the drum line) in which no note is ever clear, giving a sharp contrast to the percussive rhythms created by the snare and tenor line. 3-5 drums tuned to different notes and muffled, most often used in runs in which, while the rest of the band is playing, are heard 'below' the winds. Being described as 'off the chain' or 'sick' while in a bass line is commonplace, and should be treated as such.
The 1989 Santa Clara Vanguard bass line was 'off the chain.'
