Multi-Chord Pro: Chord & Ear
Multi-Chord Pro is an interactive music training game for chord construction, note spelling, staff reading, ear training, and fretboard or keyboard relationships. Have you ever seen Cmaj7, F#7, or Bbmaj9 and struggled to name the notes inside? Can you play a chord shape but still feel unsure whether you can hear the difference between a block chord and an arpeggio? Multi-Chord Pro turns chord theory into practical training. Start with a chord symbol, work out its chord tones, read the notes on the grand staff, enter the correct spellings, and listen to the chord or arpeggio immediately. It is designed for guitarists, bassists, pianists, songwriters, arrangers, music students, and anyone who wants a stronger foundation in harmony. KEY FEATURES • Chord Tone Construction Identify roots, thirds, fifths, sevenths, extensions, and altered tones from chord symbols. • Grand Staff Reading See chord tones on treble and bass clefs to strengthen the connection between note names, pitch, and notation. • Accurate Note Spelling Practice correct theoretical spelling with sharps, flats, double sharps, and double flats. • Chord and Arpeggio Ear Training Listen to block chords and arpeggios separately to develop harmonic recognition and interval awareness. GAME MODES • Practice Mode Choose roots and chord types freely. Practice with drone tones, a metronome, block chords, and arpeggios. • Timed Challenge Answer as many questions as possible within a time limit. • Speed Challenge Complete a target number of questions in the shortest possible time. • Stage Mode Progress through structured stages, from basic triads to seventh, ninth, eleventh, thirteenth, suspended, sixth, and altered dominant chords. • Weakness Training Focus on chord types that need more practice based on your answer history. • Mistake Training Review questions from your mistake bank. Correct answers are removed as you improve. MORE PRACTICE TOOLS • Bass fretboard, guitar fretboard, and piano keyboard references. • Custom fretboard skins, note display options, and mirror mode. • Tap answer slots or note buttons to hear notes and check your work. • Daily missions, weekly missions, achievements, personal statistics, seven-day accuracy, and missed-chord analysis. • Timed and speed challenge history to track your progress. • Traditional Chinese, Simplified Chinese, English , Korean and Japanese support. • Core gameplay is available offline. Whether you practice for a few minutes a day or use it as part of a serious music routine, Multi-Chord Pro helps you see chords, hear chords, and spell every note with confidence.

Installs
How many people have installed this game, as the storefront reports it. This number is worldwide — unlike the price, the same package answers with the same install count in every market we asked — so it carries no country. Each source below is a different kind of number and they are never drawn on one axis.

Google Play shows “5+” on the store page.
Play publishes a precise install counter alongside the rounded step users see on the store page. This is that counter, worldwide, as it stood each day we asked.
Of the eight storefronts we track, only Google Play publishes an install count we can read. Where a store publishes nothing of the kind, this panel shows nothing rather than a zero.
