Speaking of ToT, I think that'd be a good song to look at now as an example.
Your assignment is to figure out the chords I used in that song. Note that not every single note will fall into a chord (notes that don't are appropriately called "non chord tones" or NCTs). All the chords are either major or minor triads, and each bar has either 1 or 2 chords in it. For major chords, just put the root of the chord, and for minor chords, put the root followed by a lowercase m. Don't worry about what key it's in, or resolution of dissonances or any of that stuff, just tell me the chords. Also, don't worry about enharmonics (i.e. distinguishing between F#/Gb, C#/Db, etc.).
I'll give you the first 16 bars to get you started:
