Bassline - Walking Bass

A walking bass is a style of bass accompaniment or line, common in baroque music and jazz, which creates a feeling of regular quarter note movement, akin to the regular alteration of feet while walking. Thus walking basslines generally consisting of unsyncopated notes of equal value, usually quarter notes (known in jazz as a "four feel"). Walking basslines use a mixture of scale tones, arpeggios, chromatic runs, and passing tones to outline the chord progression of a song or tune, often with a melodic shape that alternately rises and falls in pitch over several bars. To add variety to a walking bassline, bassists periodically interpolate various fills, such as playing scale or arpeggio fragments in swung eighth notes, plucking muted percussive grace notes (either one grace note or a "raked" sequence of two or three grace notes), or holding notes for two, three, or four beats. Some songs lend themselves to another type of variation: the pedal point, in which the bassist holds or repeats a single note (often the tonic or the dominant) under the chord changes.

Walking basslines are usually performed on the double bass or the electric bass, but they can also be performed using the low register of a piano, Hammond organ, tuba or other instruments. They can also be sung. While walking bass lines are most commonly associated with jazz and blues, they are also used in rock, rockabilly, ska, R&B, gospel, latin, country, and many other genres.
