I would be interested in lessons that give us a bunch of vocabulary about a specific field. The fields i am interested in are:
Baseball (base, run, hit, inning, etc.)
Classical Music (symphony, movement, tempo, composer, conductor, etc.)
Fine Art (visual art) (art terms of all sorts, descriptive words)
Movies (technical terms)
etc.
It would be great to know a lot of words about each of these fields. Then I could discuss them with my Japanese friends!
