treat ～だ as a particle お↑とうと↓だ が↑くせいだ か↑だ for downstep patterns, both mora of です attach low あ↓きです お↑か↓しです for heiban the pitch drops only after the で が↑くせいで↓す か↑で↓す みたい　(looks like) has similar rules for downstep: あ↓きみたい お↑か↓しみたい お↑とうと↓みたい for heiban: が↑くせいみ↓たい か↑み↓たい ーだろう also has some rules for downstep: お↑とうと↓だろう お↑か↓しだろう for heiban it only drops after the ろ： が↑くせいだろ↓う か↑だろ↓う でしょう・らしい follow these rules: downstep お↑か↓しらしい・お↑か↓しでしょう heiban が↑くせいでしょ↓う・が↑くせいらし↓い か↑でしょ↓う・か↑らし↓い this らしい is for the "seems like" meaning. The "i heard meaning" of らしい, all nouns become heiban like this: に↑ほんじんらし↓い even though にほんじん usually is なかだか THis gives us things like あ↑きらし↓い for (i heard it is autumn) CONJUGATIONS OF ADJECTIVES All なかだか 3 mora i-adjectives　（あ↑つ↓い、な↑が↓い、た↑か↓い） have their pitch drop moved one mora back in all conjugations: あ↓つさ、あ↓つければ、あ↓つかった For most 4 mora nakadaka i-adjectives the downstep stays the same place in conjugations: か↑わい↓い、か↑わい↓いくて、か↑わい↓かった、か↑わい↓さ Also counts for 5 mora nakada i-adjectives: お↑もしろ↓い、お↑もしろ↓くて、おもしろ↓さ ATAMADAKA i adjectives stay atamadaka in conjugations: よ↓い、よ↓かった、よ↓ければ、よ↓さ HEIBAN i adjectives (軽い、赤い so on） are often said as nakadaka by younger people but their conjugations are still unique: あかい turns into あ↑かく、あ↑か↓くて、あ↑か↓かった、あ↑か↓ければ、あ↑かさ Think of it as staying heiban in あ↑かく and あ↑かさ conjugations and having the drop stay the same place as the one in the nakadaka "version" of the dictionary form For na-adjectives: The さ forms are all you need to think about other than remembering the pitch of the original word: heiban stays heiban: た↑いへんさ、じゅ↑んすいさ All downstep na-adjectives will become odaka with the drop before the sa: げ↓んき becomes げ↑んき↓さ、ゆ↓たか becomes ゆ↑たか↓さ、　さ↑わ↓やかー＞さ↑わやか↓さ and so on FOR ALL I-ADJECTIVES: The ～な↓い form always attaches high to the normal 〰く form of a given word: よ↓く↑な↓い。 for heiban this is of course just あ↑かくな↓い All further conjugations of the ない keep the downstep after the な. for example: あ↓つく↑な↓かった 〰な↓る also attaches this way：あ↓つく↑な↓る、あ↑かく↑な↓る FOR NA-ADJECTIVES: 〰じゃ↑な↓い attaches き↑れいじゃ↓ない、げ↓んきじゃ↑な↓い、す↑き↓じゃ↑な↓い the downstep in じゃない stays the same in all conjugations: ～げ↓んきじゃ↑な↓かった CONJUGATIONS OF VERBS: Most conjugations of Heiban stays heiban: と↑める、と↑めて、と↑めた、と↑めない、と↑めながら、と↑めれる、と↑めさせる TWO MORA verbs are also heiban idiot! 泣く for example. *For 〰ます and 〰ました conjugations of heiban words there is a downstep after the ま: あ↑そびま↓す、な↑きま↓した For 〰ません and　〰ませんでした conjugations of heiban words the downstep is after the せ：　あ↑そびませ↓ん、な↑きませ↓んでした for the 行こう kind of conjugation for heiban words the downstep occurs one mora before the う: と↑めよ↓う, あ↑そぼ↓う for the 〰たい conjugation for heiban words the downstep occurs after the た：　あ↑そびた↓い、な↑きた↓い everything below the "*" until this line counts for non heiban verbs as well. :) やったー BACK TO HEIBAN verbs: なかった form has a drop after the な：　と↑めな↓かった for the 〰れば form the drop is after the れ or eqv. mora: あ↑そべ↓ば、と↑めれ↓ば、　な↑け↓ば For the command form there is a drop after the last mora of the verb: あ↑そべ↓よ、と↑めろ↓よ、な↑け↓よ for the 〰ても form the drop is after the て：　と↑めて↓も、あ↑そんで↓も For the 〰たり　form the drop is after the た：　あ↑そんだ↓り、と↑めた↓り ATAMADAKA VERBS: most conjugations stay atamadaka: み↓る、み↓た、み↓て、み↓れば、み↓ろ、み↓ても、み↓たり、 ーながら　conjugation has the drop after the な：　み↑な↓がら み↑れ↓る、み↑られ↓る、み↑させ↓る forms all have the drop after the second to last mora. For the negative conjugations the drop is before the な：　み↓ない、の↑ま↓ない、の↑ま↓なかった NAKADAKA VERBS ながら form drops after the な　and ーれる、ーさせる　and ーられる form also have their drops after the second to last mora (rules like atamadaka) For example: お↑よぎな↓がら、お↑よげ↓る、お↑よがせ↓る、お↑よがれ↓る For negative conjugations the drop is after the mora before the な：　た↑べ↓ない、た↑べ↓なかった　・　は↑しら↓ない、は↑しら↓なかった The past　（たべた）, the if (たべれば), and the て form (たべて） all have their drop on the third to last mora: た↓べた、は↑し↓った、お↑よ↓いだ = past た↓べて、は↑し↓って、お↑よ↓いで　＝てFORM た↑べ↓れば、は↑し↓れば、お↑よ↓げば =if form Command form = the drop is after the second to last mora in the word: た↑べ↓ろ、は↑し↓れ、お↑よ↓げ、 ーても form = the drop is after the fourth to last mora: た↓べても、は↑し↓っても、お↑よ↓いでも SENTENCE LEVEL PITCH ACCENT： when heiban elements are put together the latter's rise disappears: 私は+日本語(...) becomes わ↑たしはにほんご(...) pitch stays high until a downstep occurs (even with the start of odaka or nakadaka words, the rise is "removed") べ↑んきょう＋し↑て＋い↑ま↓す becomes べ↑んきょうしていま↓す の RULE の particle generally removes a final syllable downstep from multisylable words (even counts for stuff like き↑の↓う or に↑ほ↓ん、 because のう and ほん are syllables.) for example the words: に↑ほ↓ん、や↑ま、き↑の↓う with の attached become: に↑ほんの、や↑まの、き↑のうの THis is not consitent however か↑わ↓の and　か↑わの are apparantly both right(?) and words like せんせい never become heiban with the no afterwards. it also mainly counts for odaka words This rule also does not affect words that express quantities. for example ご↑に↓ん or ひゃ↑く↓ don't become へいばん when followed by a の
