1. What is the significance of the line that connects at two chords or notes together at the bottom?
2. The second and third notes in the first bar are connected with a curved line with an "H" over it. Is this a hammer-on or something else?
3. In the fourth measure, two notes are connected with a curved line with a "Po" over it. Is this a pull-off or something else?
4. Throughout the music the first thru third strings are played 3-0-0 and 2-3-2. There are also patterns on the first and second strings of 3-0 and 2-3. I do not recognize these are chord patterns. Are they?
5. Above the bars there are letters - G, D, G, C, G? I assume they are chords but they do not show in the tab. What is their significance?
