Interval Ear Trainer

An ear-training exercise: two notes play and you name the interval between them, from a minor second to an octave. It trains recognising intervals by ear for instrument practice or music theory.

How to use

1. Choose "Direction", "Intervals" (beginner, intermediate or choose your own), "Register" and the number of "Questions". Changes apply from the next question.
2. Press "Start": two notes play. "Replay" plays the same notes again.
3. Answer with an interval button or the number-row key printed on it. The result, the two note names and a reference-song example appear at once.
4. Press "Next" for the next question; at the end the accuracy and best streak are summarised.
5. Check "Accuracy by interval" below for weak intervals; "Clear statistics" starts the record again.

How it works

• The notes are a soft synthesised tone in equal temperament with A4 = 440 Hz (one semitone = the twelfth root of 2).
• Intervals are counted in semitones, from the minor second (1) through the perfect fourth (5), tritone (6) and perfect fifth (7) to the octave (12).
• Beginner asks the major second, major third, perfect fourth, perfect fifth and octave; intermediate asks all twelve. The same interval is never asked twice in a row.
• Settings and statistics are saved only in this browser. Sound plays only after you press a button; no microphone is used.

Questions and answers

Which intervals should I practise first?

Start with the beginner set in the ascending direction. When the accuracy is steady, switch to intermediate or use "Choose" to drill only the intervals you confuse.

What do ascending, descending and together mean?

Ascending plays the lower note first, descending the higher note first, and together sounds both at once. "Mixed" picks one of the three at random for each question.

Why is there one button for the tritone?

The augmented fourth and the diminished fifth are both six semitones and sound the same, so they share one button.

What are the reference-song examples?

The first two notes of a well-known folk or classical tune that opens with that interval, for example "Twinkle, Twinkle, Little Star" for the perfect fifth. The songs are not played.

Where are the statistics stored?

Only in this browser on this device; nothing is sent anywhere. "Clear statistics" deletes them.
