Language Note
Hangul is one of the world's most systematic writing systems — every syllable is built from three components: an initial consonant (초성), a vowel (중성), and an optional final consonant (종성). Language Note draws on that structure to map each jamo to a unique piano pitch, turning any Korean sentence into a one-of-a-kind chord progression. Whether you're learning Korean or simply curious about the relationship between language and music, dive in and listen.
Hangul Chord Conversion
19 initial consonants, 21 vowels, and 27 final consonants each map to a unique pitch in the G2–B4 range, forming instant chords.

Jamo to Note Reference Chart
Every Korean jamo maps to a specific piano pitch. Consonants (initial & final) anchor the chord in the lower register (G2–F#4), while vowels colour the harmony in the mid register (C4–B4).

Anatomy of a Hangul Syllable
Every Hangul syllable follows the pattern Initial consonant + Vowel + (optional) Final consonant. Take '한' (Han): it breaks down into ㅎ (A2) + ㅏ (C4) + ㄴ (F#3), producing a three-note chord that sounds all at once.
