Identifying intervals by ear is not about "good ears" but about turning hearing into something you can count. Every method does the same job: use a stable intermediary to translate the distance between two notes into information.

Three intermediaries, easiest to strongest

One: anchor melodies. Attach one piece to each interval, one that opens with it, and match what you hear against that. The limit is that the anchors must be memorised and cover only a few common intervals.

Two: comparison by size. Stop trying to name the interval and measure the width first: is this wider or narrower than a perfect fifth? Wider or narrower than a major third? Place each interval relative to one you already know — "narrower than an octave, wider than a fifth" — and close in from there. This method never expires, because size is what an interval essentially is (see semitones and whole tones).

Three: scale degrees and key. Read intervals inside a tonal frame: hearing two notes, judge which degrees of the key they are. It demands a firm sense of key first, but once it is in place both speed and accuracy rise sharply.

A workable order

StagePractiseReady when
1unison and octaveyou can tell "the same note" from "the same name an octave apart"
2seconds (semitone / whole tone)you can separate the two narrowest distances
3thirds (major / minor)you can hear bright versus dark — the most valuable step of all
4fifths and fourthsyou can at least group "the hollow ones" without subdividing yet
5sixths and seventhsyou can derive them from "how much wider than a fifth"
6augmented and diminishedlast, and it needs [[concept:consonance

Stage 3 is the hinge. Once thirds are secure, most other intervals can be derived by relative position.

Listen: turn identification into comparison

The point here is not naming but comparing: hear the fourth and the fifth to fix a sense of what sits between them, then hear a major third. "Much narrower than a fifth" turns out to be a reliable description in itself.
