Ear Training for Intervals: A Method You Can Practise Daily

On this page

Learn intervals in small sets, anchored to a tonic, and sing each one before you name it. Start with three intervals that sound clearly different, and add a fourth only when the first three are reliable in random order. Practise for about ten minutes a day, and keep a record of what you miss. The method below rests on those habits. The reference melodies support them and do not replace them.

#Start with three intervals that sound different

Intervals group by sound, and the groups tell you where to start. Perfect consonances, the perfect fourth, fifth and octave, sound open and stable. Thirds and sixths sound sweet, with the major ones bright and the minor ones dark. Seconds and sevenths sound rough or restless. The tritone, six semitones wide, sounds unstable, because it asks to resolve. A beginner should begin with the groups whose members are easy to tell apart, not with the hardest interval on the chart.

A good first set is the perfect fifth, the major third and the minor second. The fifth is open, the major third is bright, and the minor second is tense, so the three differ in size and in character at once. Once those three are reliable, add the minor third and the perfect fourth. The sixths and sevenths come later, because they are easy to mishear as their inversions, the thirds and seconds. The tritone comes last, because it is the most unstable of the set and is its own inversion.

The same groups appear on the page, where reading intervals at sight trains the eye to recognise them. The point of a small set is that every interval has a distinct sound. If you can only name two of the three, the set is not finished. Keep practising it until the answer comes from the sound and not from a guess that happens to be right.

#Tie each interval to a tonic, and sing before you name

An interval heard in isolation has no home. Anchor it to a tonic instead. Play the tonic, play the second note, then return to the tonic. The tonic gives the interval a place in the scale, so the top note becomes a scale degree you can name by its function: the fifth, the third, the fourth above the tonic.

The drill below stays on C4 throughout. Each pair is a tonic followed by an interval above it, returning to the tonic each time. It runs a perfect fifth, a perfect fourth, a major third and an octave.

Sing the top note before you name it. Sing it on a neutral syllable, or on the solfège syllable the scale degree would take (the scale degrees and solfège article lists them), so the voice produces the interval. The singing is the check. If the sung note matches the recording, the ear has taken the interval in. If the name comes first, the ear tends to confirm the label rather than the sound.

#Attach each interval to a reference you already know

Reference melodies are scaffolding. They give the ear a sound to hold, and they must be ones you can sing from memory without looking. The table pairs each interval with a cue from the solfège or from a tune whose opening you know well.

The first phrase of “Happy Birthday” in C contains two of these intervals: a major second, heard up and then back down, and a perfect fourth up to F. Sing it, then check each step against the table.

Two cautions. First, the solfège cues work in any key, but the tune cues are written in C, so they work only there. In another key, transfer the tune’s shape by scale degrees, not by letter names. Second, the cue is a memory aid, not a definition. An interval is the distance between two notes, and the tune is just one place it occurs.

#Practise melodic and harmonic, direction first

Melodic intervals come one after another, and harmonic intervals sound together. Most listening is melodic, because a tune delivers its intervals one at a time. Both need practice, and the harmonic version is harder because two notes blend. Chords deliver their intervals together, so the harmonic version is the one that tests whether the ear can separate the notes it hears. Play the pair together, listen for the blend, and decide whether it sounds open or dark, stable or restless. Then play the same two notes one after the other and check the result.

This drill plays four harmonic pairs above C4. They are a minor third, a major third, a tritone and a perfect fifth, in that order:

Decide the direction before you decide the size. A fifth above a note and a fifth below it are different intervals, so the direction is part of the answer. The inverse of a perfect fifth is a perfect fourth, the same two notes with the lower one moved up an octave. Many errors come from hearing the right pair of notes and then labelling the wrong direction.

#Where this misleads people

The most common error is confusing the minor third with the major third, because both are “thirds”. Use the character from the table as well as the size. A bright third and a dark third sound different even when both are held as a chord, so check the quality as well as the count of semitones.

The second is naming by the reference. A cue such as “Twinkle” gives you the fifth only in the key where the tune starts on C. If you name the interval by the tune’s position rather than by the sound, the answer fails in other keys. Name the interval from the tonic, and treat the tune as a check.

The third is mishearing the tritone and the seventh. Both are unstable, and both can be taken for a neighbouring interval, the fourth and the octave respectively, when they are played low or quickly. Slow them down, sing the top note, and listen for the pull toward resolution.

The fourth is counting semitones on a keyboard instead of listening. Counting works in the first few sessions, and it is a useful check after you have answered. As a method, it trains the fingers. A listener working from a recording has no keyboard in front of them, so the ear has to make the judgment on its own. Use the keyboard to confirm an answer, never to produce it.

#A ten-minute routine and a progress log

Use the same routine every day. It has four parts, and the whole thing takes about ten minutes.

1. Sing the tonic, then sing each interval in your set above it. Thirty seconds.
2. Play each interval melodically from the tonic, sing the top note, and name it. About five minutes.
3. Play the harmonic pairs in the same set, decide direction and quality, then check. About two minutes.
4. Ask a partner, or use the ear training studio, to play the set in random order. Write each answer down. About three minutes.

Once the set is reliable, the same listening skill drives transcribing by ear. Keep a log with the date, the set, and the intervals you missed in step four. Review the log once a week. If the same interval keeps appearing, slow that interval down and give it an extra minute. Add a new interval only when the set is correct in random order on several days in a row, because a set that is right only in order has been memorised, not learned.

Questions

How long does it take to learn intervals by ear?

The time depends on how often you practise, but progress comes from consistency. Add a new interval only when the current set is reliable in random order, not when a calendar says it is time.

Which interval should a beginner learn first?

Start with a perfect fifth, a major third and a minor second. They differ clearly in size and in character, so they are hard to confuse. The octave and the perfect fourth are also easy to start with.

Do I need perfect pitch to learn intervals?

No. Interval work trains relative pitch, the ability to hear the distance between two notes. Naming an absolute note is a separate skill, and intervals are learned by their sound relative to a tonic.

Why sing an interval before naming it?

Singing makes the ear produce the interval, so the sound is held in the voice and can be compared with the recording. Naming first invites guessing from a label rather than listening to the sound.
