How practice works

A practical ear training routine

Ear Trainer is built around short, repeatable listening sessions. Each exercise plays synthesized piano tones in the browser, asks you to identify what you heard, and keeps score so you can notice patterns over time.

Intervals

Intervals teach the distance between two notes. Start with a few familiar shapes like major thirds, perfect fifths, and octaves, then add smaller steps once those sounds feel stable.

Chords

Chord practice focuses on color and tension. Major, minor, diminished, augmented, suspended, and seventh chords each have a different emotional pull that becomes easier to recognize with repetition.

Scales

Scale recognition trains the mood of a whole pattern. Modes, pentatonic scales, blues, whole tone, and diminished sounds all leave different clues in the ear.

Suggested practice

Practice for five to ten minutes at a time, keep the first sessions narrow, and sing the answer internally before clicking. Accuracy matters more than speed. When a sound becomes obvious, add one or two new choices and keep listening for contrast.
