What if learning music theory actually felt like playing?

Most theory apps feel like homework. ChordIQ turns note reading, chord recognition, and ear training into a game you actually want to play — with scores, streaks, and a global leaderboard to keep you coming back.

Read notes on sight
Identify notes on treble, bass, and alto clef. Learn key signatures for major and minor scales. Build real reading fluency — not just memorization.
Train your ear
Recognize intervals, identify chords by sound, and tell major from minor in real time. Ear training that sticks because you're competing, not just repeating.
Compete and track progress
Climb the World Chart leaderboard. See how your skills stack up against musicians everywhere. Every session counts.

30+ game modes. One app.

Reading

  • Sight-Reading Notes

    Identify notes on treble, bass, alto and grand staff. Timed rounds build speed, plus Marathon and Survival runs for the brave.

  • Key Signatures

    Identify key signatures for major and minor scales on bass and treble clef. Know your sharps and flats on sight.

  • Note Finder

    Find any named pitch on your keyboard or fretboard against the clock. Instrument fluency, not just theory.

Rhythm and singing

  • Rhythm Training

    Read a notated rhythm and tap it in time across ten complexity levels. A one-time latency calibration keeps your device delay out of the score.

  • Rhythm Echo

    Hear a rhythm and tap it straight back. No notation, pure internal pulse.

  • Sing & Match the Pitch

    Sing or play a note into the microphone. A live cents meter scores how precisely you hold it — real vocal pitch training, on both iOS and Android.

Ear training

  • Ear Training & Intervals

    Recognize intervals, chords and notes by sound alone — the skill every other one rests on.

  • Perfect Pitch

    Name a single note with no reference tone. Levels widen the note set and octave range as your absolute pitch sharpens.

  • Melodic Dictation

    Hear a short melody in an established key and tap it back in order. The classic conservatory exercise, timed and scored.

  • Solfège & Scale Degrees

    Hear a diatonic note in a key and name its scale degree. Movable-do, so it transfers to any key.

Chords, scales and theory

  • Chord Recognition

    Two Chords, Major or Minor, and Chord Qualities — from fast triad calls up to m7b5, sus4 and extensions.

  • Chord Progressions & Cadences

    Hear a progression and pick its Roman numerals. Name the cadence: authentic, plagal, half or deceptive.

  • Circle of Fifths & Theory

    Answer on an interactive circle-of-fifths wheel, build named chords note by note, and transpose on the clock.

  • Guess the Scale

    Recognize major, natural and melodic minor, pentatonic, blues and modal scales — on the staff or by ear.

  • Play Chords & Scales

    Play the named chord or scale on an on-screen keyboard or guitar fretboard. Connect a MIDI keyboard for a hands-on run.

Competition

  • World Chart Leaderboard

    Compete with musicians globally. Track your scores, climb the rankings, and see your progress over time.

I have problem when it comes to reading written music. I think ChordIQ is helping me overcome the anxiety and I am beginning to understand the names of the lines and spaces of the stave. With more practice I think I will be able to get better at reading. Thank you team ChordIQ!

Just perfect. This is learning in a fun way. Still exploring the app as there's lots of different areas but very intuitive. Ear training, learning intervals, reading bass clef, treble clef or both at once. Don't bother looking anywhere else, this app will keep you happy. My kids, 11 & 13 year old just see it as a fun game so it's not just for the oldies like me!

This app is really helping me to read notes and recognize key signatures more quickly. It makes it like a game and I noticed that after I'd been using this app for a couple of weeks but not practicing piano, I was able to read sheet music and play more easily and quickly than before.

Awesome app! I learned bass clef super fast, I love all of the games, especially the scale note reading ones. Super effective. I haven't been using it long but I haven't found any major problems yet. Nonetheless, the games are super effective and fun. Would definitely recommend.

Bought many apps in the past and this one is by far the most complete and fun I’ve tried so far. The support is also first class. Fast and responsive (thanks Sergey). The price is a bargain (compared to other apps doing only half this one can) Keep it up Team ...

This app is exactly what I was looking for!! I recently starting going to private piano lessons every week but seemed to not be very good at reading the notes straight away, so I searched for an app so I can practice before my next lesson and this is perfect. You can take quizzes for treble and bass cleft notes and chords etc, keep track of your high-score, how many you got correct and it has a leaderboard showing people with the highest scores. You can also take listening tests: My piano teacher would listen to me playing a song without looking at the keys I was playing and could even point out the notes I played wrong USING JUST HER EARS and that amazes me, so with this app maybe I could do that too.

Did you ever ask yourself how to learn notes best? This is a great way to do it. this app got multiple games in it that revolve around chords and notes. With the „guess notes“ game i managed to learn fast and easy, because it‘s simple and fun- and you can do it anytime you got some spare minutes. Also the devs are really good with helping out if you got any trouble. 5/5!

Frequently asked questions

What is ChordIQ?

ChordIQ is a music training game that teaches sight-reading, ear training, rhythm, singing and music theory through fast-paced interactive challenges. It includes more than 30 game modes covering staff reading, chords, scales, theory, ear training, singing and rhythm. You read notes on treble, bass and alto clef, identify key signatures, tap notated rhythms in time, sing into the microphone to match a pitch, train perfect pitch, take melodic dictation, and recognize chord progressions and cadences. The app supports piano, guitar, ukulele, and bass, and works with external MIDI keyboards for a hands-on experience. ChordIQ is available on iOS and Android. Whether you are a beginner learning to read notes on the staff for the first time or an intermediate musician sharpening your theory and ear, ChordIQ turns practice into a game you actually want to play. Track your scores on the global World Chart leaderboard and see how you rank against other musicians.

What game modes does ChordIQ have?

ChordIQ includes more than 30 game modes, grouped by skill area. Staff reading: Guess Note on treble, bass, alto and grand staff, plus Marathon and Survival runs, Note Values, Rests and Key Signatures. Rhythm: read a notated rhythm and tap it in time at ten complexity levels, or hear a rhythm and echo it back, with a one-time latency calibration so your device audio delay is not scored as an error. Singing: sing or play a notated note into the microphone, or hold a pitch in Match the Pitch while a live cents meter scores your precision. Ear training: Guess Note by ear, Intervals, Chords by ear, Perfect Pitch with no reference note, Chord Qualities, Solfege scale degrees and Melodic Dictation, where you tap back a melody you just heard. Chords: Two Chords, Major or Minor, Major and Minor Chords played on the instrument, Guess Chord, Play Chord and Inversions. Scales: Guess Scale and Play Scale across major, natural and melodic minor, pentatonic, blues and modes. Theory: Circle of Fifths, Chord Progressions in Roman numerals, Cadences, Build the Chord and Transposition. Plus Note Finder, a timed drill for locating any pitch on your keyboard or fretboard. Each mode has its own scoring and World Chart ranking.

Is ChordIQ free?

ChordIQ is free to download and play on iOS and Android, and the great majority of its 30+ game modes are free, with ads between rounds. ChordIQ Pro removes those ads and also unlocks the custom practice modes, where you pick your own note, interval, chord, scale and rhythm sets, along with saved user libraries, the Inversions trainer and the daily-plan reroll. It is sold as a yearly subscription, a weekly subscription, or a one-time lifetime purchase; where the store offers one, the yearly plan starts with a 3-day free trial. Subscriptions auto-renew through the Apple App Store or Google Play and can be cancelled at any time from your device settings.

Does ChordIQ support MIDI keyboards?

Yes. ChordIQ supports external MIDI keyboards on both iOS and Android, allowing you to play chords and notes directly on a physical keyboard instead of the on-screen interface. On iOS, connect via the Lightning or USB-C Camera Connection Kit or use a Bluetooth MIDI controller. On Android, connect via USB OTG. Once connected, ChordIQ detects your MIDI keyboard automatically and routes input to the active game mode. This is especially useful in the Play Major Chords and Play Minor Chords modes, where tapping on a real keyboard feels more natural and helps build muscle memory. MIDI support works with any class-compliant MIDI controller — no additional drivers or setup required. If you already own a MIDI keyboard, ChordIQ gives you a practical reason to use it for structured practice.

Can I try ChordIQ without installing it?

Yes. The free music games at songtive.com/en/games run in any browser and need no account. Each one is a short scored round of the same training the app runs — note reading on the staff, chord recognition, ear training. They are a fair sample of the app, not a demo with the good parts removed. ChordIQ itself is free to download on iOS and Android and adds more than thirty game modes, MIDI keyboard input and the World Chart leaderboard.

What instruments does ChordIQ support?

ChordIQ supports four instruments: piano and keyboard including external MIDI controllers, guitar, ukulele, and bass. In the Play Chords game modes, you tap notes on an on-screen keyboard or guitar fretboard matched to your chosen instrument. Sight-reading, key signature, and ear training modes work across all instruments since they focus on universal music theory concepts like note identification, interval recognition, and scale knowledge. If you connect a MIDI keyboard, ChordIQ uses it for the piano and keyboard modes. Guitar and ukulele players benefit from the fretboard interface that shows chord shapes in standard tuning. The app is designed so that the theory skills you build — reading notes, recognizing chords by ear, identifying scales — transfer directly to whichever instrument you play in real life.
