Free Ear Trainer — Learn to Recognize Music Intervals Online

October 24, 2026 · 2 min read · By the DollarWise team

Can you tell a perfect fifth from a major third by ear? This free ear trainer plays two piano-like notes and asks you to name the interval — the foundation of relative pitch. Three difficulty levels, streak tracking, replay-on-demand, and instant feedback. Everything runs in your browser with synthesized WebAudio tones — no audio files, no downloads.

How it works

Hit Play interval — the tool synthesizes two piano-like notes in sequence using the WebAudio API (no audio files needed). Pick the interval you heard from the multiple-choice buttons: unison, minor/major 2nds and 3rds, perfect 4ths and 5ths, tritones, 6ths, 7ths, and octaves depending on difficulty. Each answer gets instant feedback with a memory-hook tip (e.g. the minor 2nd is the Jaws theme), and your streak and history build up on the scoreboard.

Everyday uses

  • Music students — drill interval recognition for theory exams and aural tests.
  • Guitarists & pianists — learn to pick out melodies and chords by ear.
  • Singers — build the relative pitch that makes sight-singing easier.
  • Producers — transcribe basslines and riffs without hunting note-by-note.
  • Curious listeners — finally understand what musicians mean by “a perfect fifth”.

Tip: start on Easy until you can nail the unison, 2nds, 3rds, 5th and octave — those five carry most pop melodies. Then turn on descending intervals: they’re the real test.
