About this app

ChordCue is an interactive app for learning modern (jazz & pop) chords by **hearing, seeing, and understanding them through scale degrees.**

Tap any chord to get instant representations:
• Sound — block-chord and arpeggio playback
• Keyboard — chord tones highlighted on a piano with note names and degrees (1, b3, #11, …)
• Staff — notated on the treble clef with accidentals (flats and double-flats included)
• Guitar — auto-generated fingering diagrams on a standard-tuning fretboard (browse positions and shapes, plus a minimal-voicing view)

Highlights
• 34 chord qualities — from triads and sevenths to major/dominant/minor extensions and altered tensions
• Four grouping modes — by type, by note count, by characteristic degree, or diatonic (a key's 7 chords + progression playback)
• Guitar fingering diagrams — a playable voicing for any chord at every position, with multiple shapes per position to toggle
• Diatonic & progressions — the 7 chords of the current root as a major/minor key, with ii–V–I and other progressions to play
• Accurate note spelling — it writes Eb, not D#. Degree-based spelling gives the right note name in context
• Horizontal swipe picker for all 12 roots — check a chord in any key instantly
• Korean & English, switchable inside the app

Built for players and songwriting learners who want to master chord theory systematically.
