Ear Training Foundations

Lesson 2 of 4

Hearing Intervals

The second ear-training skill: recognizing the distance between two notes. Learn why direction matters and how to practice ascending and descending intervals.


Once a single note feels stable, the next skill is hearing the distance between two notes — the interval. Intervals are the building blocks of melody, and recognizing them is what lets you transcribe a line or play it back by ear.

Size and direction

An interval has two properties your ear needs to learn:

  • Size — how far apart the notes are, from a semitone up to an octave and beyond.
  • Direction — whether the second note is higher (ascending) or lower (descending).

Direction matters more than people expect. A descending minor sixth doesn't sit in the ear the same way an ascending one does, even though the size is identical. Train both.

How to practice

  1. Start with big contrasts. A small step versus a wide leap is easy to tell apart — begin there.
  2. Add neighbors gradually. Once large differences are automatic, introduce intervals that sit close together.
  3. Separate the directions. Practice ascending and descending as distinct skills.

Don't lean on song references forever. They're a useful crutch at first, but the goal is to hear interval size directly — which is exactly what focused daily reps build.

Where this leads

Intervals connect everything. Stacked together they become chords; strung in sequence they become melodies and scales. With notes and intervals under your ear, you're ready to start hearing harmony.

Next up: stacking intervals into chords and learning to hear major, minor, and beyond by color.
