What Music Interval Trainer does, with a checked example

Plays a pair of notes and asks you to name the musical distance between them - major third, perfect fifth, and so on - then scores the answer and serves the next pair. You can focus a session on a subset of intervals, and the notes can be played one after another or together, upward or downward. The thing most first-timers get wrong is that an interval name carries two facts at once: the size (how far apart) and the quality (minor, major, or perfect). The ear has to catch both, and a missed answer usually collapsed them into one.

Worked example

A concrete input and expected output from the current implementation.

Input

The tool plays two notes, C4 and then G4. Answer submitted: Perfect fifth.

Expected output

Marked correct; the score increases by one. The played pair spans seven semitones, which is named the perfect fifth.

The tool generated the pair, so the answer key is fixed: C4 to G4 is seven semitones, and that distance is the perfect fifth. The submitted name matches the played notes, so the round is scored correct.

How the result is produced

1

Question generation

The tool picks a starting pitch and an interval from the set you have enabled, then plays the two notes: ascending or descending, one after another or together, per your settings. Because the pair is a fixed number of semitones apart, the same interval lands in different registers from round to round - deliberate, so you learn the distance itself rather than one familiar pair of notes.

Scoring and feedback

The correct answer for each round is fixed by the notes that were played, and your answer is checked against it. Correct answers add to the score; a miss is recorded, so the score tracks how reliably you identify the enabled intervals. Because the interval set is a setting, a high score against two easy intervals means less than the same score against the full octave.

Good uses

  • Drilling the exact interval pairs before an aural-skills exam or a lesson test, until the names come without thinking.
  • A singer or instrumentalist practicing a part whose entries start a fixed distance from the melody, so the entrance is heard rather than guessed.
  • A songwriter checking a melody by singing each leap and fall back to the tune, catching the places where the interval in the head does not match the interval on paper.

Limits and checks

  • Names come from spelling, not just distance: six semitones is an augmented fourth if spelled C to F sharp and a diminished fifth if spelled C to G flat, and the same ambiguity exists for every interval size. The audio alone cannot show which one the tool intends, so a name that fits your context can still be marked wrong.
  • Intervals past the octave reduce to their simple form: a major tenth sounds like a major third because the extra octave is the same note class. Very low and very high registers also make judging harder than mid-range. A drill that stays inside one octave never tests these effects, so they will still surprise you in real music.
  • The score only means what the settings allow: a perfect run with the set narrowed to thirds and fourths proves you hear those, and says nothing about sevenths or the octave. Widen the drill set, and a dropping score is progress being measured honestly, not a regression.

Common questions

Can this teach me perfect pitch?

No. Interval training builds relative pitch: the ability to hear that a second note sits a specific distance above or below the first. Naming an isolated note with no reference is a different skill - absolute pitch - and interval drill does not reliably produce it; most working musicians never acquire it.

Why did it mark my answer wrong when I heard the tritone?

The tritone, six semitones wide, can be spelled as an augmented fourth (C to F sharp) or a diminished fifth (C to G flat); the music around it decides which is correct. The drill's answer key must choose one spelling, so your answer can be marked wrong even when you heard it exactly right. Try the other name before doubting your ear.
