Interval Ear Trainer
Hear the distance between two notes and name it — ascending, descending or together.
What it trains
Interval Ear Trainer plays two notes and asks you to name the interval between them. You choose which intervals are in play, whether they are played upward, downward or at the same time, and how the difficulty grows. A reference mode lets you compare any two intervals side by side whenever you want to.
- Recognising every interval from the minor 2nd to the octave, including the tritone
- Hearing intervals melodically (one note after the other) and harmonically (together)
- Telling apart intervals that are easy to confuse, such as major and minor 3rds or perfect 4ths and 5ths
Exercises
- Ascending intervals
- The lower note plays first, then the upper note.
- Descending intervals
- The upper note plays first, then the lower note.
- Harmonic intervals
- Both notes play together.
- Mixed
- Any of the three, chosen at random each time.
- Compare (reference mode)
- Pick two intervals and play them from the same starting note, one after the other, as often as you like.
Try it
A short interactive demo built from the same code as the real tool.
Settings you can change
- Custom interval sets: tick exactly the intervals you want, and save sets to reuse
- Adaptive difficulty: starts with a few clearly different intervals and adds more as your accuracy rises, or eases back if it drops
- Direction: ascending, descending, harmonic or mixed
- Starting note: random, or always from C
- Register: low, middle or high
- Tone: keyboard or plucked guitar
- After a wrong answer: hear your answer and the right answer back to back
- Session length
Instruments and clefs
Keyboard and plucked-guitar tones. After each answer the interval is shown on the treble staff and the piano keyboard.
Reference view
The compare view plays any two intervals from the same note, with both shown on the staff and keyboard.
Who it’s for
- Players who want to recognise intervals by ear, whether they play guitar, piano or something else
- Students who find some intervals easy and others hard, and want practice weighted towards the hard ones
Who it isn’t for

- Players looking for compound intervals and chord-based ear training (those are in the Atelier Edition)
