The correct answer is walking bass.

Explanation:

A walking bass is a musical accompaniment pattern typically used in jazz and some forms of popular music. This pattern features a steady quarter-note rhythm, where the bass line moves in a stepwise manner, often outlining the chord changes of the song. It creates a sense of movement and harmonic underpinning, guiding the rhythm and enhancing the overall groove of the music.

In contrast, the other options refer to different musical concepts. "Eight-to-a-bar" generally refers to a rhythm in which eight notes fit into one measure, "ostinato" denotes a repeated musical phrase or rhythm, and "cadenza" refers to a solo passage typically demonstrating the technical skill of the performer. Walking bass, therefore, is the term that best describes the steadily-moving accompaniment pattern in string bass.
