Hey Kevin. In the sixteenth bar of the verse, there will be a walk up, but it is specific. The chord is a one chord, but the bass notes walk up 1 3 5 to the 6 note which is in the bass of the four chord. I repeat that later and use an arrow to denote the walk up (arrows usually mean walk up, if we have a glissando (slid) most folks write a curved line up or down to or from a number. The underline with an arrow is a redundancy, once a pattern is established, I usually leave out redundancies. I wrote this chart out real time and didn't make any changes, I would leave it like this for a session or live show unless it needed more detail.

You can read a dozen different number charts and find a dozen different systems, but after reading them for a while, it's no problem. Some folks underline a split bar, some put a box around it, some put it in parenthesis, some just put a slash between the numbers (which, to me, can be confused with having a chord with a specific bass note...for that I just write one note over another in roughly the space where one note would be. I'll dig out someone else's charting of a song and show some differences.

You've got to know your limitations. I don't know what your limitations are. I found out what mine were when I was twelve. I found out that there weren't too many limitations, if I did it my way. -Johnny Cash
