How does pitch accent work in Japanese?


My studies taught me there's two ways to say each mora in Japanese, with the
way you normally talk and when you put a bit more emphasis on a mora, i.e.
when someone says なつかしい, the word would be sounded out as na-tsu-ka-SHI-i.

I know only one dictionary that shows the way the words are emphasized (the
Pocket Kenkyusha Japanese Dictionary), and I feel it uses overly complex
terminology to get the point across. I want to able to put the principles into
terms ordinary folks can understand, but every resource I have is either too
complicated or tells me that the language doesn't put any emphasis on
individual mora, which I know is totally wrong.

So, how _does_ pitch accent work in Japanese?




You may be familiar with the concept of sentence-level pitch changes in
English; for example when you are asking a question, you end the sentence with
a rising pitch to indicate that it is indeed a question. Japanese also has
sentence-level pitch changes, but more relevantly to this question, it has
_word-level_ pitch changes.

# Downstep Notation

In the standard (Tokyo) dialect, word pitch accents are realized by something
called a "downstep". The pitch of a word increases until the downstep, at
which point the pitch drops.

Downsteps happen strictly between kana (the linguistics term being "mora"),
not in the middle of a kana.

These pitches can sometimes be used to distinguish words with the same
spelling. The canonical example is はし which is three-way ambiguous between 箸,
橋 and 端.

These words can be disambiguated in speech as follows:

  * 箸 (chopsticks) is はꜜし, namely the first kana must be pronounced high to facilitate the following drop
  * 橋 (bridge) is はしꜜ, the first kana pronounced low, the second high to facilitate the drop before the following kana (e.g., a particle in the sentence) which would be pronounced low.
  * 端 (edge) is はし, or "accentless", meaning that all characters are said at around the same pitch (including any following kana).

# "Binary" (LHL) Notation

You may see an alternate "binary" notation for pitch accents which is composed
of a series of "L"s and "H"s. For example, you would notate the はし words as
follows:

  * 箸 (chopsticks) is HL(L)
  * 橋 (bridge) is LH(L)
  * 端 (edge) is LH(H)

However this notation is a little extraneous when it comes to succinctly
marking the pitch accent of the word in the Tokyo dialect, because it always
follows the pattern: start low (unless the downstep is right after the first
kana), be high until the downstep, then stay low.

When discussing other dialects, sometimes more than just downsteps are
required to analyze what is going on.

# Number Notation

To find pitch accents for Japanese words, I'd say the best online resource is
大辞林.

For example, [the 大辞林 entry for
箸](http://dic.yahoo.co.jp/dsearch?enc=UTF-8&p=%E3%81%AF%E3%81%97&dtype=0&dname=0ss&stype=0&pagenum=1&index=115656400000)
says はし with a subscript "1" to its right.

It uses yet another notation, where the number works as follows:

  * if the number is 0, it is an "accentless" word, i.e., does not have a downstep
  * if there is no number, the downstep is placed after the last kana
  * if it is any other number, the downstep is placed after that kana (hence 1 for 箸)

**There is[a nice picture relating this number notation to the binary
notation](http://www.sanseido-publ.co.jp/publ/dicts/daijirin_ac.html) provided
by 三省堂, along with a number of example words.**

* * *

In the end, I'd say the downstep notation is the most succinct and expository
notation when trying to notate standard Japanese pitch accent, but learning
these other notations is useful to understand material about pitch accent.
