Perfect Pitch Test

Listen to a note and find it on the keyboard. Identify 10 notes as fast as you can!

How It Works

A note will play — click the matching key on the piano
Correct guesses advance immediately
Wrong guesses show the correct key briefly, then the missed note is added to the end
Toggle note labels on or off for an extra challenge
Your total time is recorded when all 10 notes are correct

🎵 What Is Pitch?

Pitch is how high or low a sound is. A bird's chirp is a high pitch. Thunder is a low pitch. When you sing "do, re, mi," each note is a slightly higher pitch than the one before.

On a piano keyboard, pitch goes from low on the left to high on the right. Try it — tap these buttons to hear the difference:

🌊 Pitch and Frequency

Sound is made by vibrations — when something vibrates (like a guitar string or a speaker), it pushes air molecules back and forth, creating invisible waves that travel to your ear.

Frequency is how fast something vibrates, measured in Hertz (Hz) — the number of vibrations per second. A note vibrating 440 times per second is written as 440 Hz — that's the note A, the note orchestras use to tune up!

The faster the vibration (higher frequency), the higher the pitch sounds. The slower the vibration (lower frequency), the lower the pitch. It's that simple!

🎹 What Creates Different Notes?

Every note on the piano has its own specific frequency. Here are some examples:

C = 262 Hz D = 294 Hz E = 330 Hz A = 440 Hz

Notice the pattern — as you go up the keyboard, the frequency number gets bigger. Each note vibrates a little faster than the one before it.

Here's a cool thing: when you double a frequency, you get the same note but one octave higher. Middle C is 262 Hz. The C one octave higher is 524 Hz — exactly double! That's why they sound so similar even though one is higher.

🎸 Why Do Instruments Sound Different?

A piano and a guitar can play the same note (same frequency), but they sound different. Why? Because each instrument produces extra vibrations called overtones or harmonics on top of the main note. These give each instrument its unique tone color (musicians call it timbre, pronounced "TAM-ber").

Think of it like voices — you and your friend can both sing the same note, but your voices sound different because of the unique shape of your throat, mouth, and chest. Instruments work the same way!

Choose Your Level

Beginner uses only the white keys (C, D, E, F, G, A, B) — the natural notes. Advanced adds the black keys (sharps and flats) for all 12 notes in the octave.

Each level has its own leaderboard!
