Interval Recognition

A free listening tool with twelve practice sets, covering every interval size from a minor second to an octave: minor and major seconds, thirds, sixths and sevenths, perfect fourths and fifths, the tritone and the octave. Every pair has middle C (C4) underneath, with both piano notes played together.

A harmonic interval has two notes sounding together. A melodic interval has notes played one after another. This tool uses harmonic intervals only; the higher note is always above C4, but it does not play later.

A minor third spans three semitones; a major third spans four. From C4 they are C4 with E flat4 and C4 with E4. You may hear the minor third as darker and the major third as brighter, but those are subjective listening hints, not definitions.

Yes. Open Listen and learn for labelled examples from the current set. Press Hear to highlight that example’s two keys on the piano and play them together, including black keys for flats and sharps. The guide is available before and during practice, but never follows the hidden quiz answer. Guide playback does not unlock answering: use Play to hear the question first.

Get five correct answers in a row. A mistake resets the streak, while correct and incorrect totals remain visible. After a congratulations screen, the next set opens automatically; it waits if the page is hidden or audio is playing. Next is beside Play, and Stay on this set lets you continue practising. All twelve sets are also freely selectable. Choosing a set restarts its streak; counts and completed-set marks last only for this page visit.

Each small batch contains every interval in the current set twice, in a shuffled order. The sequence never plays the same interval three times in a row, even across batches. Repeats can still occur, so it does not simply alternate. Each page visit starts with a fresh shuffled batch.

The shared Salamander sampled grand piano. Both notes start together after their samples load. Sample loading needs an internet connection. Stop, Escape, switching sets or hiding the page cancels playback. Failed or stopped question playback cannot unlock a new answer.

This is fixed-C4 listening practice, not a test of recognising intervals from every starting note. It helps you become familiar with these specific piano sounds. It does not certify mastery or claim exam-board alignment.
