How the Singing Grader Works

The tool listens to your voice and scores it on three measurable parameters that vocal coaches actually use:

• Pitch accuracy — how close your notes are to true pitch, measured in cents (±5 cents is considered professional)
• Tone consistency — how stable your tone holds across a sustained note, including vibrato regularity
• Rhythmic precision — how well your phrasing matches a steady beat

These three combined produce your 1-to-10 score. Anything subjective — your “tone colour” or “style” — is intentionally left out, because those depend on genre and taste, not measurable accuracy.

How to Use It

1. Click the record button and allow microphone access
2. Sing any phrase for 15 seconds — a chorus from a song you know works best
3. Wait about 5 seconds for analysis
4. Read your 1-to-10 score plus the per-parameter breakdown

For the most accurate result, use headphones (so the microphone only hears your voice, not the backing track or reference notes) and record in a quiet room. Phone microphones work — they’re calibrated for the human voice — but a USB or condenser microphone gives cleaner results.

What the Score Means

Score	Skill Level	What It Reflects
9–10	Professional / advanced	Pitch within ±5 cents, stable tone, locked rhythm
7–8	Strong amateur	Mostly accurate pitch, occasional drift
5–6	Average untrained	Pitch hits the right note but drifts ±20–50 cents
3–4	Pitch-uncertain	Notes recognisable but consistently off
1–2	Significant pitch difficulty	Unable to match target pitch reliably

Most untrained adults score between 5 and 7 on their first attempt. A score of 3 or below doesn’t mean you can’t learn to sing — it usually means you’ve never had the pitch-matching feedback that’s needed to improve. With practice using a pitch accuracy test, most people gain 1–2 score points within a few weeks.

What This Tool Doesn’t Measure

It’s worth being clear about what a singing grader can and can’t do.

It measures objective accuracy. Pitch is either close to the target frequency or not. Rhythm is either on the beat or not. These are mathematical comparisons.

It does not measure musicality. Bob Dylan and Tom Waits would score badly on pure pitch accuracy and still be considered great vocalists. Their genius is in interpretation, phrasing, and character — things no algorithm can rate.

It does not predict commercial success. Great singing is a combination of accuracy, tone, emotion, and style. The grader rates the technical foundation. The rest is artistry.

Treat your score as a measurement, not a verdict.

Why Pitch Accuracy Is the Foundation

Among the three things the grader measures, pitch accuracy is the most important. A 2012 study in the Journal of Voice found that pitch accuracy alone explained more than 80% of the variance in how listeners rated singing quality. Tone and rhythm matter, but they sit on top of pitch — singers who can’t reliably hit the right note can’t compensate with great tone.

This is why nearly every vocal training program — from classical conservatories to modern apps — starts with ear training and pitch matching. Once pitch is locked in, everything else (breath, dynamics, expression) becomes possible.

Other Vocal Tests on This Site

If you want to test specific elements of your voice rather than your overall singing, these focused tools work well alongside the grader:

• Vocal range test — find your lowest and highest singable notes
• Voice type test — identify whether you’re a soprano, mezzo, alto, tenor, baritone, or bass
• Pitch accuracy test — test only pitch matching against reference tones
• High note test — measure your highest comfortable note
• Low note test — measure your lowest comfortable note

Frequently Asked Questions

How accurate is the singing grader? The tool uses fundamental-frequency analysis to compare your voice against the target pitch within ±5 cents (one twentieth of a semitone). This matches the accuracy standard used by professional pitch-correction software and vocal coaches.

Do I need a good microphone? No. A standard phone or laptop microphone works because they’re tuned for the human voice frequency range (roughly 80 Hz to 1,100 Hz for singing). Background noise affects results more than mic quality, so a quiet room matters more than expensive equipment.

Why did I get a low score? Low scores usually mean one of three things: pitch drift (your notes are sliding sharp or flat), starting on the wrong note, or recording in a noisy environment that confuses the tool. Try again in a quiet room with a song you know well.

Can the tool grade rap or spoken word? The grader is calibrated for sung melody. Rap and spoken word don’t have sustained pitched notes for it to measure, so scores won’t be meaningful.

Is my voice good enough to sing professionally? A grader score is one data point, not a career prediction. Most professional singers score 8 or above, but vocal artistry depends on tone, interpretation, stage presence, and genre fit — none of which are measured here.

Is the singing grader free? Yes — it’s fully free, runs in your browser, and doesn’t require an account or downloads. No usage limits.
