Why Train
Your Ear?

Ear training is the practice of connecting what you hear to what you know — turning raw sound into musical understanding. It's how every great musician bridges theory and feeling.

What is Ear Trainer?

Ear Trainer is a focused, distraction-free practice environment for musicians at every level. Using a synthesised piano voice, it plays intervals, chords, and scales and asks you to identify them by ear. No sheet music. No note names on screen. Just pure listening.

Sessions are short by design. Even five minutes a day builds long-lasting aural memory. The streak tracker and accuracy score keep you accountable without turning practice into a chore.

"The ear is the musician's primary instrument. Everything else — technique, theory, reading — exists in service of the sound you can imagine and reproduce." — A principle of aural musicianship

Four pillars of practice

01 — LISTEN
Active hearing
Press Play before you guess. Let the sound settle. Resist the urge to click immediately.
02 — SING
Inner voice
Hum the interval or chord tone internally. Singing, even silently, anchors pitch in memory.
03 — ASSOCIATE
Musical hooks
Enable hints to link each sound to a familiar song. Over time the association fades — the interval remains.
04 — REPEAT
Daily streaks
Short, consistent sessions beat long occasional ones. Aim for 10 questions a day to build lasting recall.

How the sound is made

Every note is synthesised in real time using the Web Audio API — no samples, no files. A stack of harmonic partials with inharmonicity modelling recreates the characteristic brightness and decay of a piano string, complete with a noise burst for the key attack transient. The result is a consistent, clean reference tone across all registers.
