How to play Chord Recognition

  1. Listen to Hear red and Hear yellow. Red plays C–E–G; yellow plays C–F–A.
  2. Start three mysteries. Listen to the chord, then choose Red or Yellow.
  3. Replay a sound whenever you want. After the round, explore Mystery for a progression with one missing chord label.

Play with a child ready to choose between two colors. You can operate the buttons while they point, name a color, or tell you their choice.

02 / Chord recognition

Which chord came back?

Meet the chord sounds, then choose which one you hear. Watch an example first, and replay any sound during practice.

Pitch Discrimination · Recognizing chord sounds

Listen to pitches sounding together and recognize the chord you heard. Colors help you learn the sound labels.

For grown-ups: building this skill

Learn more chords, remove color cues, then recognize familiar sounds in new voicings and keys.

Coaching names each target chord before hiding its label. Then try the same challenge without that preview.

Take one short turn together. Help is part of practice; a later check shows what your child can do before extra coaching.

How would you like to practice?

Start with an example whenever you need one. Take turns, and finish while it still feels good.

Watch one. Then take a turn.

Here’s how to play.

Hear a chord, then choose the color or name that belongs to it.

Choose Show me for a short example. Read each step together, then move on when you’re ready. This example has no score.

Hear each color once to get started.

Three mysteries · no time limit to answer

Make it a moment together. Use a comfortable volume, take turns, and celebrate every attempt.

One small step at a time.

Begin with two color choices and use the reference sounds freely. Mystery Chord adds harmonic context: start with I or V, move to IV or V, then mix I, IV, and V. Add a third color, remove color cues, recognize new chord voicings, and transpose to G. Yellow’s C–F–A and Mystery’s F–A–C are both the IV chord, with different notes at the bottom.

Take it off-screen.

Sing two contrasting sounds, such as a short “la” and a long “oo.” Repeat one and invite your child to identify it. Return to the game and take turns choosing the color after each chord.

Before you play

Does my child need to know note names?

No. The first game asks for a color choice. Roman numerals beside the colors identify the chord families for grown-ups.

Can we listen again before answering?

Yes. Replay the mystery or hear a labeled reference. The result records when listening help was used.

What is Mystery Chord?

It starts with a four-chord progression and one hidden label. Advance from two to three choices, longer progressions, G major, and the minor vi chord. Choose the Roman numeral for the chord you heard.

Keep the music going.

Give a short musical idea, leave room for an answer, then let your child lead. These activities bring rhythm memory, pitch exploration, and turn-taking into the same playful session.

To save completed rounds, start your child’s activity from the parent dashboard.
