Q. Are vertical lines bar or chord separators

| Vertical lines are bar lines | C | F | would be two bars

/ are beat lines but needed unless you want to specific a chord on a certain beat where the chord durations are not equal | C / / Bb7 | puts the Bb7 in beat 4

|| is a double bar line indicating a bar line (and a new section)

This would be a 12 bar blues

| C | F | C | | F | | C F7 | Em7 A7 | Dm7 / / Ab7 | G7 | C A7 | Dm7 G7 |

You can see examples of his songs look like this in the songpicker window, just highlight a song and it shows at the bottom left. You can copy and paste this text too, so it’s easy to copy a few bars and use it as a template to search for that chord progressiion.

Have Fun!
