To hear intervals by ear, learn the sound of each interval by associating it with a feeling: the perfect 5th sounds open and stable, the major 3rd sounds bright, the minor 3rd sounds dark, and the octave sounds like the same note higher. Practise by singing each interval before you play it.
How do you hear intervals by ear?
Hearing intervals by ear means recognising the distance between two notes without counting, the way you recognise a friend's voice without measuring it. It is a skill, not a talent, and it is built the same way as any other skill: by associating each interval with a distinctive sound, and then practising that association until it becomes automatic. The perfect 5th sounds open and hollow, the major 3rd sounds bright and cheerful, the minor 3rd sounds dark and sad, and the octave sounds like the same note in a higher place. The key to learning intervals by ear is to start with the easy ones and add the hard ones gradually. Most people can hear the octave and the perfect 5th almost immediately, because they are so stable and distinctive. The 3rds come next, because the major-minor difference is so emotionally clear. The 2nds, 6ths and 7ths are harder, because they are less distinctive, and the tritone is the hardest of all, because it sounds so unstable that the ear struggles to place it. A few minutes of daily practice, spread over weeks, will take you further than occasional long sessions.
How interval ear training works
The most effective method is to sing the interval before you play it. Hear the root note, imagine the second note in your head, sing it, and then check yourself against the instrument. The act of singing forces your ear to predict the pitch, and the prediction is what builds the skill: listening alone is passive, but singing is active, and the gap between what you sang and what the instrument plays is the feedback that teaches you. Start with the perfect 5th, which most people can sing accurately after a few tries, and move on to the major 3rd, the minor 3rd and the octave. Another useful method is to associate each interval with a quality rather than a song. The perfect 5th feels open and empty, the major 3rd feels bright and warm, the minor 3rd feels dark and narrow, the perfect 4th feels like a question, and the tritone feels like a wobble that wants to settle. These associations are personal, and the ones you invent yourself will stick better than the ones someone else gives you, so pay attention to what each interval feels like to you and write it down. The interval calculator gives you the correct answer to check against, and the C major scale gives you a ladder of intervals to practise on.
Worked example — hearing the 3rds. Play C on the piano, then sing the note you think is a major 3rd above it, E, and check yourself by playing the E. The major 3rd should feel bright and settled, like the first two notes of a major chord. Now play C again, sing the note you think is a minor 3rd above it, Eb, and check yourself. The minor 3rd should feel darker and narrower, like the first two notes of a minor chord. Alternate between the two, major then minor, until you can sing either one without hesitating, and then try the same exercise from G, where the major 3rd is B and the minor 3rd is Bb. The C major guitar chord and the C minor guitar chord contain the two intervals.
How to practise hearing intervals
Practise in short daily sessions of five to ten minutes, and always sing before you check, because the singing is the training.
- Play a root note, sing a perfect 5th above it, then check yourself on the piano, repeating until you can sing the 5th accurately every time.
- Play a root note, sing a major 3rd, then a minor 3rd, and check both, aiming to feel the brightness of the major and the darkness of the minor.
- Ask a friend or use the interval calculator to play a random interval, guess its name before you look, and keep a score of your correct answers.
- Sing the intervals of the C major scale in order, from the root to each degree, and name each interval as you sing it.
- Practise one new interval a week, adding it to the ones you already know, rather than trying to learn all twelve at once.
Common mistakes
- Only listening, never singing — Listening alone does not train the ear, because it is passive. Singing the interval before you hear it is what builds the skill, so always sing first and check second.
- Learning intervals from songs only — Song associations help at first, but they tie the interval to one melody instead of to its sound. Learn the quality of the interval itself, so you can recognise it in any context.
- Practising for too long at once — Ear training is tiring, and after ten minutes the ear stops learning and starts guessing. Short daily sessions beat long weekly ones, every time.
Quick reference
This table gives each interval a feeling rather than a song, so you can learn to recognise it by its character instead of by a melody you happen to know. The descriptions are a starting point: pay attention to what each interval feels like to you, and replace any description that does not match your own hearing with one that does.
| Interval | How it feels | First step |
|---|---|---|
| Octave | Same note, higher up | Sing it from any root |
| Perfect 5th | Open, hollow, stable | Sing it from any root |
| Perfect 4th | Like a question waiting | Sing it after the 5th |
| Major 3rd | Bright, warm, cheerful | Sing it from C to E |
| Minor 3rd | Dark, narrow, sad | Sing it from C to Eb |
| Major 6th | Open, yearning, wide | Sing it from C to A |
| Minor 7th | Bluesy, relaxed, loose | Sing it from C to Bb |
| Tritone | Wobbly, tense, unstable | Sing it last, after the rest |
Use the table as a practice plan: start at the top and work down, spending a week on each row, singing the interval from several roots before you move on. When you reach the bottom, go back to the top and test yourself on all eight, and you will be surprised how much your ear has learned.
Frequently asked questions
How long does it take to hear intervals by ear?
Most people can hear the octave, perfect 5th and major 3rd reliably within a few weeks of daily practice, and the full set of twelve intervals within a few months. The 2nds and 7ths take longest, because they are the least distinctive.
What is the easiest interval to hear?
The octave, because it sounds like the same note in a higher place, and the perfect 5th, because it sounds so open and stable. Most beginners can recognise both within a day or two of practice.
Should I sing intervals or just listen to them?
Sing them. Singing forces your ear to predict the pitch before you hear it, and that prediction is what builds the skill. Listening alone is passive, and it improves your recognition much more slowly.
Can anyone learn to hear intervals?
Yes. Hearing intervals is a learned skill, not a gift, and almost anyone can develop it with regular practice. Perfect pitch, the ability to name a note without a reference, is rarer, but relative pitch, the ability to name intervals, is trainable for nearly everyone.
What is the best order to learn intervals?
Start with the octave and the perfect 5th, then the major and minor 3rds, then the perfect 4th, then the 6ths, then the 7ths, then the 2nds, and finally the tritone. Learn them in that order, one at a time, and add each new interval to the ones you already know.
