About this tool
Train your ear to recognise what you hear. This trainer plays a random interval or chord with the Web Audio engine and asks you to name it, then tells you instantly whether you were right and keeps a running score so you can watch your accuracy climb. Drill intervals, chord qualities or both at your own pace — a few focused minutes a day sharpens the skill surprisingly fast. Tap to start the first sound, since browsers need a gesture before they will play audio.
Frequently asked questions
What is a musical interval?
An interval is the distance in pitch between two notes — for example, the gap from C up to G is a perfect fifth. Each interval has its own characteristic sound, and learning to recognise them by ear lets you work out melodies, harmonies and basslines without sheet music. The trainer plays two notes and asks you to identify the interval between them.
How does ear training help my playing?
Recognising intervals and chords by ear is the skill behind figuring out songs without tabs, improvising lines that fit the harmony, and transcribing what you hear. Like any skill it grows with regular practice, which is why the tool keeps score: short, frequent sessions where you guess, check and repeat build reliable recognition far faster than the occasional long one.
Why is there no sound until I press start?
The notes and chords are generated live by the Web Audio API, and browsers block that audio until you interact with the page, so nothing plays until you tap start. Once it is running, each new question sounds automatically. If you still hear nothing, check that your device is not muted and that the volume is turned up to an audible level.
