Skill level of notating this?

[stillofthenight]

How many semesters of university aural skills classes would you have to go through to be able to notate the chords in this piece of music by ear?

I know this is a very simple genre of music and many academics would probably scoff at it but I would still like to know.

None.  Sounds like one line to me.  I don't think you'd need any training... assuming you'd listen and pick it out.

Otherwise, I'd say 1-2 semesters.  Sounds diatonic, repetitive pattern. Get a part of it, you get a lot.

Doing that how though?  After one listening?  Joining in playing during that one listening?  I could see someone doing that, but it would be beyond what gets taught.  That would be a couple semesters still I'd think, but a lot of outside practice. 

Ditto for theory.  Ear training can do some.  Knowing theory that goes along with that ear training will help.
