Step-by-step explanation:
Walking bass is a technique commonly used in jazz and blues music. It involves playing a steady and repetitive bass line that moves in a stepwise motion. The bassline provides a solid foundation for the rest of the music and helps to create a groove or rhythm.
For example, in a jazz trio, the bass player might play a walking bass line while the pianist and drummer improvise on top. The bassline usually consists of quarter notes or eighth notes and typically outlines the chord progression being played.
