How to read an analysis chart

Explanation

In my analytic chart, there are some of my own diagramless way.

1. II → V
2. V →I
3. Optional change (Chord) or substitute change
4. II → V substitution
5. V → I substitution
6. Modulation: “-” means minor key. If there is an arrow, it means scope of a modulation.
7. Subdominant minor: I put this mark to distinguish subdominant minor funtion.
8. Section repesat: I use this notation to express a section repeat and the number means the number of bars, because sometimes the last 4 or 8 bars are different from the previous same section, then I put the different change with this notation.
9. Deceptive cadence
10. Key(s) which are played often
