What term describes a bass line, often featured in jazz, that moves up and down a pattern of notes?

The term that describes a bass line frequently used in jazz and characterized by a steady rhythmic pattern that moves up and down a scale or chord progression is "Walking Bass." This technique creates a sense of motion and drive within the music, allowing the bass to act not just as a foundation, but also as an integral melodic component.

In a walking bass line, the bass notes typically represent each beat or subdivision within a measure, often outlining the chord structure while providing a flowing, melodic contour. This helps maintain the harmony and supports the overall groove of the piece. Walking bass lines are commonly used in various styles of jazz and can also be found in certain classical and pop music settings.

The other terms listed refer to different styles or techniques in bass playing. For instance, slap bass refers to a percussive technique often used in funk and rock genres, funk bass pertains to a specific rhythmic and harmonic style characterized by syncopation, and pedal point is a musical term referring to a sustained note while harmonies change around it, which does not specifically describe the movement typical of jazz walking bass lines.
