How to Play: Pitch Matching Game

Setup — takes 30 seconds:

1. Allow microphone access when prompted — the game needs to hear your voice
2. Allow audio output — the game needs to play reference tones through your speakers or headphones
3. Select your difficulty level: Beginner, Intermediate, or Advanced
4. Choose your vocal range: Bass, Baritone, Tenor, Alto, Mezzo-Soprano, or Soprano — the game plays notes within your comfortable singing range

Each round:

1. The game plays a reference tone — a pure sine wave at a specific musical note
2. Listen carefully for 2–3 seconds, then sing “ahhh” and try to match the pitch exactly
3. Hold your note steady for 3 seconds while the game measures your accuracy
4. Your score appears: the note you hit, the target note, and your cents deviation
5. Green = within ±10 cents (professional standard), Yellow = ±10–25 cents (good), Red = ±25+ cents (keep working)

Scoring: Each round scores 0–100 points based on cents accuracy. Perfect match (0–5 cents) = 100 points. The game tracks your cumulative score across a session and shows your accuracy trend — are you getting closer with each round?

Pitch Matching Game Modes

Beginner — Single Note Matching

One note plays at a time, within the centre of your selected vocal range. The note sustains for 3 seconds before you sing. A visual pitch guide appears on screen while you sing, showing whether your voice is above or below the target. This mode is the starting point for anyone new to pitch training — it builds the fundamental ear-voice connection before adding any complexity.

Best for: Singers who are new to pitch training, children learning to sing, and anyone who has been told they sing “off key” and wants to start correcting it.

Intermediate — Note Sequences

Two to three note sequences play in succession. You sing each note back immediately after hearing it. No visual guide during singing — you must rely on your ear memory alone. This trains not just pitch matching but short-term tonal memory — the ability to hold a pitch in your mind while your voice finds it.

Best for: Singers who can match single notes reliably and want to build melodic accuracy for real songs.

Advanced — Interval Jumping

The game plays two notes separated by a musical interval — a third, a fifth, an octave — and you sing both notes back in sequence. This is the hardest mode because you must accurately reproduce both the individual notes and the distance between them. Interval accuracy is the foundation of singing melodies correctly.

Best for: Intermediate and advanced singers working on sight-singing, harmony, or vocal performance accuracy. Pairs naturally with the interval ear training exercises for a complete ear training programme.

Sprint Mode — 60 Seconds

60 seconds, as many notes as possible. One note at a time, scored on speed and accuracy combined. Your highest Sprint score is saved and displayed as your personal best. This mode is for competitive practice — trying to beat your own record builds focused, high-intensity ear training sessions.

Best for: Regular practice sessions where you want a fast, motivating workout rather than a methodical drill.

Why Pitch Matching Is the Foundation of Singing Accuracy

Most singers who struggle with intonation don’t have a “tone deaf” problem — they have an ear-voice connection problem. The ear hears a pitch correctly, but the voice doesn’t reproduce it accurately. These are two separate skills:

Pitch perception — hearing and recognising a pitch correctly. Most people have adequate pitch perception. You can tell when a note sounds wrong even if you can’t say why.

Pitch production — controlling your voice to reproduce a specific pitch accurately and consistently. This is the skill that varies enormously between singers and improves most rapidly with targeted practice.

Pitch matching games train both simultaneously. You hear a pitch, attempt to reproduce it, and immediately see whether your voice matched — the feedback loop that builds the neural connection between what your ear hears and what your voice produces. Research in motor learning consistently shows that immediate, specific feedback accelerates skill acquisition faster than practice without feedback. The game provides that feedback in a format the brain learns from efficiently.

This is also why simply “singing along to songs” doesn’t build pitch accuracy as quickly as targeted matching exercises — there’s no isolated feedback on each specific note, and the complexity of a full song makes it hard to isolate which notes are off.

What Your Score Tells You

Consistently flat (always scoring below the target note) Your voice is defaulting to a lower pitch than you intend. The most common causes: insufficient breath support — your air pressure is too low to reach the target pitch, so your voice settles flat rather than climbing to the note. Also common with tired voices, unwarmed voices, and singers who habitually “scoop” up to notes from below. The fix: approach each note with more air and a slightly higher intention. Use the pitch accuracy checker to monitor whether you improve across a session.

Consistently sharp (always scoring above the target note) Your voice is reaching above the target pitch. Common causes: too much effort or tension — singers who try hard often overshoot because excess muscle activity raises pitch. Also caused by singing too loudly, which increases subglottal air pressure and sharpens pitch. The fix: sing with less effort, at a slightly softer volume, and aim your mental target slightly lower than where you think the note is.

Random scatter (sometimes sharp, sometimes flat, unpredictably) Pitch instability — your voice isn’t anchoring to notes consistently. Most often caused by insufficient breath support, singing in an unwarmed state, or fatigue. Noise from your environment can also cause the game to misread your pitch — ensure you’re in a quiet room. For detailed troubleshooting, see the why does my pitch detector give unstable readings guide.

Accurate in the middle but falling off at extremes Your supported range is narrower than your full range. Notes within your comfortable tessitura are accurate; notes approaching the edges go off pitch. This is completely normal — work on the middle range first, then use the how to extend vocal range guide to expand the accuracy zone outward gradually.

Pitch Matching vs Ear Training — What’s the Difference?

These terms overlap but describe slightly different things:

Pitch matching specifically means reproducing a pitch you’ve heard — listening to a note and singing it back at the same frequency. It’s a voice-production skill.

Ear training is the broader practice of developing musical hearing — recognising intervals, identifying chord qualities, hearing key centres, distinguishing rhythmic patterns, and more. Pitch matching is one component of ear training.

This game trains pitch matching — the most fundamental ear training skill and the right starting point for most singers. Once single-note matching is reliable, the natural progression is to interval recognition, which is covered in the interval ear training exercises. From there, scale degree recognition, chord quality identification, and melodic dictation build a complete musical ear.

Practice Guide — How to Use the Game Most Effectively

Session length: 10–15 minutes per session is optimal for most people. Beyond 20 minutes, vocal and mental fatigue decreases accuracy and slows learning. Short, regular sessions (daily or every other day) outperform long infrequent ones.

Warm up first: Always warm up your voice before playing. A cold voice has reduced accuracy and the game scores lower not because your ear is off, but because unwarmed vocal cords don’t respond as precisely. 5 minutes of gentle humming, lip trills, or scales is enough. The vocal warmup exercises guide has a quick pre-session routine.

Use headphones when possible: Playing the reference tone through speakers while your microphone is open can create feedback — the speaker sound enters the mic and confuses the pitch detection. Headphones send the reference tone directly to your ears without the mic picking it up, which dramatically improves accuracy and eliminates false readings.

Start easier than you think you need to: Most singers overestimate their current accuracy. Start in Beginner mode and establish a baseline score before progressing. Progressing too quickly means you’re practising inaccuracy rather than accuracy.

Track your score across sessions: Write down your average score from each session — even a rough note in a phone. Seeing gradual improvement is motivating and helps you identify whether specific conditions (time of day, how warmed up you are, hydration) affect your performance.

Combine with the pitch accuracy checker: Use the game for the ear-voice training loop, then use the pitch accuracy checker for an objective scored baseline of your current intonation accuracy. Use both regularly to track improvement from two angles.

Pitch Matching for Specific Situations

Choir singers

Choir intonation depends on each singer’s ability to match their pitch to the section and to the harmonic context. The game’s intermediate mode — singing back sequences — directly trains the skill of locking onto a note you’ve heard from another voice. The advanced interval mode trains the ability to sing harmonically above or below a given pitch, which is exactly what inner-voice parts require.

Beginners and children

The beginner mode is designed to be accessible with zero music theory knowledge. You hear a sound, you sing it back, you see whether you matched it. No labels, no theory, no reading required. The visual guide in beginner mode gives immediate, readable feedback that children respond to particularly well.

Singers who’ve been told they’re “tone deaf”

True tone deafness (amusia) is rare — affecting roughly 4% of the population. Most people who believe they are tone deaf actually have a disconnect between their hearing and their voice production that can be improved with targeted practice. The beginner mode starts exactly where this training needs to start: a single note, immediate feedback, simple repetition. Many singers who believe they are tone deaf show measurable improvement within a few weeks of regular pitch matching practice.

Musical theatre and performance singers

Performance accuracy requires maintaining pitch accuracy under adrenaline and physical movement — conditions that differ significantly from quiet practice. Once you’ve built reliable accuracy in the game, practise while standing, moving, and even with deliberate distractions, to make the accuracy robust across performance conditions.

How the Game Detects Your Pitch

When you sing, your microphone captures the audio signal. The game uses the Web Audio API and the YIN pitch detection algorithm to identify the fundamental frequency of your voice — the lowest and most prominent repeating component of your vocal sound, which determines the perceived pitch.

That detected frequency is compared to the target note’s mathematical frequency (defined by the A4 = 440 Hz equal temperament standard). The difference between your frequency and the target is calculated in cents and displayed as your accuracy score.

The algorithm runs at approximately 60 frames per second and takes a rolling average across 2–3 seconds of sustained singing to produce a stable score, rather than scoring the instant you start (which would penalise the natural attack before the note stabilises). All processing happens locally in your browser — no audio is recorded, stored, or sent anywhere.

Frequently Asked Questions

What is a pitch matching game? A pitch matching game plays a reference tone and listens through your microphone as you sing it back, then scores how accurately you matched the pitch in cents — hundredths of a semitone. It trains the ear-voice connection that underpins singing accuracy.

Do I need any music knowledge to play? No. The beginner mode requires nothing except the ability to make a sound with your voice. You hear a tone, you sing it back, you see whether you matched it. The game handles all the musical analysis automatically.

How do I improve my score? Consistent short sessions beat infrequent long ones. Always warm up before playing. Use headphones to avoid mic feedback. Start in beginner mode and build accuracy before progressing. Track your scores across sessions — gradual improvement is the goal, not a high first-session score.

Does it work on iPhone and Android? Yes. Open in Safari on iPhone or Chrome on Android, allow microphone and audio access, and play immediately. For best results on mobile, use headphones with an inline microphone to avoid the reference tone being picked up by the device mic.

Why does my score jump around unpredictably? Usually caused by background noise interfering with pitch detection, singing too softly, or holding notes too briefly. Move to a quieter room, sing at a comfortable supported volume, and hold each note for at least 3 seconds. See the troubleshooting guide for specific fixes.

Am I tone deaf if I score very low? Almost certainly not — true tone deafness affects roughly 4% of the population. Most low scores reflect an untrained ear-voice connection that improves with practice. Start in beginner mode and track your score over two weeks of regular sessions before drawing any conclusions about your ability.

What is the difference between this and the pitch accuracy checker? The pitch accuracy checker measures your accuracy against specific target notes during free singing — it shows you how accurate you are right now. The pitch matching game actively trains accuracy through a listen-and-reproduce loop — it improves your accuracy over time. Use the pitch accuracy checker to measure, and the pitch matching game to train.

Can this replace singing lessons? No — a game can’t replace the personalised feedback, technique coaching, and holistic musicianship development of a good teacher. But it can significantly accelerate pitch accuracy improvement between lessons, and it gives you objective data to bring to your teacher about which notes and intervals you’re struggling with most. For guidance on lessons, see the best online singing lessons guide.

Is my audio recorded? No. All processing happens locally in your browser using the Web Audio API. No audio is uploaded, recorded, or stored anywhere. See the privacy policy for full details.
