Train your ear to name any interval
Hear two notes, name the gap between them. Pick a difficulty, choose ascending, descending or harmonic, and build the skill that makes transcribing, tuning and writing by ear feel effortless. Your streak and accuracy are tracked as you go.
How to practise
A few focused minutes a day beats one long session a week.
Start at Beginner
The beginner pool keeps it to four very distinct intervals so your ear learns the clear landmarks first. Press Play and listen.
Name what you hear
Pick the interval from the buttons. Get it right and your streak grows; get it wrong and the tool replays the correct interval so you can lock in the sound.
Level up when it feels easy
Move to Intermediate and Advanced as your accuracy climbs, or use Custom to drill the exact intervals you keep missing.
Switch direction
Once ascending feels solid, try descending and harmonic. Recognising an interval played as a chord is a different skill, and a vital one for hearing harmony.
Why interval training matters
Intervals are the alphabet of melody and harmony. Every melody, bassline and chord is just a set of intervals stacked together. Once you can name them by ear, you stop guessing and start hearing music the way it is actually built.
It is the fastest route to playing by ear. When you can recognise a perfect fifth or a minor third instantly, working out a song becomes a matter of hearing the gaps rather than hunting for notes one at a time. Transcribing goes from painful to quick.
It makes you a better producer and mixer. Hearing intervals sharpens your sense of tension and resolution, helps you spot when a melody clashes with a chord, and makes writing counter-melodies and harmonies far more intuitive.
Short and regular wins. Ear training rewards consistency over marathon sessions. Five minutes a day, a few weeks in a row, will do more than an occasional hour. The streak counter here is there to make that daily habit a little more satisfying.
The twelve intervals
Every interval is simply a number of semitones from the starting note. This is the ladder your ear is learning to climb.
Red marks the perfect intervals (unison, fourth, fifth, octave) — the most stable and easiest to spot first.

Questions, answered
What is an interval?
An interval is the distance in pitch between two notes, like a major third or a perfect fifth. Naming intervals by ear is the foundation of playing, transcribing and writing music by ear.
What is the difference between ascending, descending and harmonic?
Ascending plays the lower note then the higher one, descending plays the higher note then the lower one, and harmonic plays both at the same time. Each trains a slightly different listening skill, and harmonic is the hardest.
Which level should I start with?
Start at Beginner. It uses four very distinct intervals so your ear learns the clearest landmarks first. Move up to Intermediate and Advanced as your accuracy improves, or use Custom to drill specific intervals.
How often should I practise?
Little and often. Five focused minutes a day will build your ear faster than one long weekly session. The streak counter is there to help make it a daily habit.
Do I need headphones?
Headphones or decent speakers help, especially for harmonic intervals and the wider gaps, but any device that plays sound will work.
Is it free?
Yes, completely. No account, no download, no limits. Press Play and start training.
