When you change the bass note, the role of each note in the chord will shift in relation to that note

Hello again!

These are methods that crop up all over popular music, and will help your songwriting skills to develop, as well as your bass playing.

Let’s take another look at our notes in a major key arranged in a circle, as seen in Figure 1 to our right. Remember that we built triads and then added extensions—7ths, 9ths, 11ths, and 13ths—to those chords by just ‘following the star’ in the diagram, and then we looked at the way that the bass note defines the nature of the entire chord.
