While it is easy to use a dictionary to determine a pitch accent of a particular, given word, I’ve been (at quite beginner’s level) yet unable to find any concise source discussing the general patterns and rules. Having pitch accent as a topic that interests me both practically (to enhance my speech) and theoretically, as my philological research centers around the mora and tonal stress, I am unaware even of where to find the discussion of verbal paradigms concerning their stress.
Having a historical exposition of its derivation from Middle Japanese would also be great.
Can someone point me to some literature discussing the detail of pitch accent in particular, and especially in general linguistic point-of-view?
