Interval ear training
Two notes play. Name the distance between them. Start with a small set, then add intervals as your accuracy climbs above 90%.
Use headphones if you can. Keyboard: Space = play/next, R = replay, 1–9 = answer.
How to practise intervals so it sticks
An interval is the distance between two pitches, counted in letter names (the “number”) and semitones (the “quality”). Recognising them by ear is the foundation of melodic dictation, sight-singing and playing by ear.
- Start small. The starter set (perfect 4th, perfect 5th, major 3rd, octave) contains intervals that sound very different from each other.
- Sing it back. After each answer, hum both notes. Producing the interval yourself links the sound to a physical sensation.
- Listen for quality, not just size. Major 3rds and 6ths sound bright; minor ones sound darker. The tritone sounds unstable and wants to resolve.
- Add one interval at a time. When your accuracy stays above 90% for 20 answers, turn on the next one in Settings.
- Switch direction. Descending and harmonic intervals are separate skills. Practise them once ascending feels easy.

Questions
How do I start ear training intervals?
Start with two contrasting intervals, such as the perfect 4th and perfect 5th, or the major 3rd and octave. Once you score above 90% over 20 questions, add one more interval. Adding intervals one at a time is far more effective than guessing among all twelve from day one.
Should I practise ascending, descending or harmonic intervals?
All three. Ascending is easiest and is where most people start. Descending intervals are needed for melodic dictation, and harmonic intervals (both notes at once) are tested in most graded aural exams. Switch the playback mode in Settings.
Do reference songs actually help?
Yes, as a starting crutch. A song cue like “Here Comes the Bride” for a perfect 4th gives you something to compare against. Over time, aim to recognise the sound of the interval itself, because songs are slow to recall under exam pressure.
How long does it take to learn intervals by ear?
Most learners who practise 10 minutes a day can reliably identify all ascending intervals within a few weeks. Consistency matters more than session length: short daily sessions beat one long weekly one.
