1. Master Diacritical Map: Phonological Marking of Vowel i
Lĭttle Jack Frost went up the hĭll,
Watchĭng the stars and the moon so stĭll,
  Watchĭng the stars and the moon so brīght,
  And laughĭng alone wĭth all hĭs mīght.
Lĭttle Jack Frost ran down the hĭll,
Late ĭn the nīght when the wĭnds were stĭll,
  Late ĭn the fall when the leaves fell down,
  Red and yellow and faded brown.
Short ĭ (/ɪ/) Breve: Little, hill, still, with, his, in, winds, -ing Long ī (/aɪ/) Macron: bright, might, night (Trigraph -igh-)

3. Science of Reading & Poetic Structure

Orthography of Trigraph -igh-

In bright, might, and night, the silent letters gh mark historical Germanic palatal/velar fricatives [ç]/[x]. Through compensatory vowel lengthening, the vowel became long diphthong /aɪ/.

Meter & Phonological Rhyme

Couplets AABB (hill/still, bright/might) and CCDD (hill/still, down/brown) foster prosodic reading fluency and reinforce the phonological word families -ill, -ight, and -own.
