Hear How Far the Notes Travel
An interval is the distance between two notes. You have heard thousands of them in every song you know; this page helps you notice them on purpose, one comparison at a time.
Distance before names
Interval names such as "perfect fifth" or "minor sixth" can feel like a foreign vocabulary list. Set them aside for now. Begin with a simpler question: which of two pairs travels further? Play two notes, then two other notes, and decide which gap is wider. When that feels easy, make the two gaps more similar.
The unit of distance in Western music is the semitone, the smallest step between neighbouring keys on a piano, black or white. Two semitones make a whole tone. Twelve semitones make an octave, where the upper note sounds like a higher copy of the lower one — think of a man and a child singing "the same" note together.
Melodic and harmonic intervals
When two notes are played one after the other, the interval is melodic. When they are played together, it is harmonic. Melodic intervals are usually easier at first because you can follow the movement. Harmonic intervals ask you to hear two notes inside one blended sound, which is a separate skill — practise it later and kindly.
Harmonic intervals are often described as consonant (smooth, settled) or dissonant (rubbing, wanting to move). These are descriptions of tension, not quality judgements. A tight minor second can be beautiful, and composers rely on it to create suspense.
Interval comparison table
Reference tunes help some listeners and confuse others. Use them as reminders of a contrast you already hear, not as a test. All references below are the rising interval at the start of the melody or of the named phrase.
| Interval name | Semitones | Familiar reference | What many listeners notice |
|---|---|---|---|
| Minor second | 1 | Theme from Jaws (John Williams) | Very close, rubbing, tense |
| Major second | 2 | "Happy Birthday" ("-py Birth-") | An ordinary walking step |
| Minor third | 3 | "Greensleeves" opening | Small leap, often shaded or wistful |
| Major third | 4 | "When the Saints Go Marching In" | Small leap, often bright |
| Perfect fourth | 5 | Wagner's Bridal Chorus ("Here Comes the Bride") | Open, announcing |
| Tritone | 6 | "Maria" from West Side Story (Leonard Bernstein) | Restless, unresolved |
| Perfect fifth | 7 | Star Wars main title (John Williams) | Wide, stable, heroic |
| Minor sixth | 8 | "The Entertainer" (Scott Joplin), the upward leap | Wide, yearning |
| Major sixth | 9 | "My Bonnie Lies Over the Ocean" | Wide, warm, sweeping |
| Minor seventh | 10 | "Somewhere" from West Side Story | Reaching, nearly an octave |
| Major seventh | 11 | "Take On Me" (a-ha), chorus leap | Almost home, slightly sharp-edged |
| Octave | 12 | "Over the Rainbow" ("Some-where") | Same note, higher |
If a reference tune is unfamiliar to you, skip it. A tune you already know — from any culture — that starts with the same leap is more useful than any list.
Ordered listening prompts: the pair comparison
Use a piano, a keyboard app or any tuning app that plays single notes. Set a comfortable volume first, and play everything yourself so nothing starts unexpectedly.
- Play a note, then the note two keys above it (2 semitones). Listen twice.
- From the same starting note, play the note seven keys above (7 semitones). Listen twice.
- Alternate the two pairs. Say "near" or "far" out loud for each.
- Now compare 3 and 4 semitones from the same start. This is the minor and major third contrast.
- Sing the upper note of each pair after you hear it. Your voice will remember the size.
- Only then read the names in the table above and attach them.
If they sound the same: that is information, not failure. Go back to a wider contrast you can hear, then narrow the gap again on another day.
A note on exams and apps
Graded music exams such as those set by ABRSM and Trinity College London include aural tests, and many apps drill interval naming. Both can help, but speed drills reward guessing. We suggest using them after a few weeks of slow comparison, when names attach to sounds you already recognise.
