"Now we're going to take a look at E flat seven which is our last chord. And, it's a seventh chord which means the seventh note of the chord is altered. But its E flat seven is found, the fifth note of the scale, one, two, three, four, five. There's E flat, right? Starting on one, two, three, four, five. Or, I can count down, one, seven, six, five. But, now we're going to make E flat our root, our one. And we get this whole new set of intervals, right? We have one, two, three, four, five. Or it can go down, one, seven, six, five, four, three, two. So again, by moving the root around, these three strings we get this huge set of intervals which helps us to build our vocabulary on the bass. So now we're going to use E flat as our root or our tonal center and we're just going to walk around the scale and just keep coming back to E flat. There's only one E flat in the low register. It's just one of those notes. So just get used to coming right back to it. So, you want to walk through, one, two, three, four, five, one, seven, six, or seven, six, five, four, three, two and then you don't have the low one there because our lowest note is E. And that's E flat on your upright bass."
