Interval Ear Trainer
Develop your ear for musical intervals with this interactive training tool. Listen to two notes played in sequence (ascending, descending, or harmonic) and identify the interval from 13 options ranging from unison to octave. Three difficulty modes gradually introduce more intervals: Easy starts with perfect 4ths, 5ths, and octaves, Medium adds 3rds and 6ths, and Hard includes all intervals. Each interval includes a reference song hint to help you remember — for example, the Perfect 4th sounds like the opening of "Here Comes the Bride." Track your progress with correct count, total attempts, and current streak statistics stored in your browser.
Interval Reference
How to Use
- 1
Select a Difficulty
Choose Easy (perfect 4th, 5th, and octave only), Medium (adds major and minor 3rds and 6ths), or Hard (all 13 intervals from unison to octave) based on your current skill level.
- 2
Listen to the Interval
Click Play to hear two notes. They can be ascending, descending, or harmonic (simultaneous) depending on the mode. Listen carefully to the distance between the two pitches.
- 3
Identify the Interval
Click the button matching the interval you heard — minor 2nd, major 2nd, minor 3rd, and so on up to octave. Reference song hints are available for each interval to help you remember.

Track Your Progress
Your score shows correct answers, total attempts, and current streak. Stats persist in localStorage so you can track improvement over multiple practice sessions.
Examples by Niche
Start on Easy mode to nail perfect intervals — P4 sounds like "Here Comes the Bride," P5 like "Star Wars" theme, octave like "Somewhere Over the Rainbow." Build to 90% accuracy before moving up.
Use Medium difficulty to practice 3rds and 6ths — the intervals most common in vocal harmony. Train with harmonic mode to hear both notes simultaneously, simulating real choral singing.
Challenge yourself on Hard with all intervals including tritone (the "devil's interval") and minor 2nd. These dissonant intervals are essential for jazz improvisation and chord recognition.
Spend 5 minutes daily on ascending intervals, then switch to descending. Track your streak over weeks — most musicians see significant improvement after 2-3 weeks of consistent practice.
Frequently Asked Questions
What intervals are included in each difficulty level?
Easy mode includes Perfect 4th, Perfect 5th, and Octave — the most distinctive intervals. Medium adds Minor 3rd, Major 3rd, Minor 6th, and Major 6th. Hard mode includes all 13 intervals: Unison, Minor 2nd, Major 2nd, Minor 3rd, Major 3rd, Perfect 4th, Tritone, Perfect 5th, Minor 6th, Major 6th, Minor 7th, Major 7th, and Octave.
What are the reference song hints for each interval?
Common reference songs include: Minor 2nd (Jaws theme), Major 2nd (Happy Birthday), Minor 3rd (Greensleeves), Major 3rd (Oh When the Saints), Perfect 4th (Here Comes the Bride), Tritone (The Simpsons theme), Perfect 5th (Star Wars), Minor 6th (The Entertainer), Major 6th (My Bonnie), Minor 7th (Somewhere from West Side Story), Major 7th (Take On Me), Octave (Somewhere Over the Rainbow).
What is the difference between ascending, descending, and harmonic intervals?
Ascending plays the lower note first, then the higher note. Descending plays the higher note first, then the lower. Harmonic plays both notes simultaneously. Ascending intervals are easiest to identify. Descending and harmonic intervals are more challenging and are important skills for transcribing real music where notes overlap.
How long does it take to develop good interval recognition?
Most music students develop reliable interval recognition within 2-4 weeks of daily 10-15 minute practice sessions. Start with Easy mode until you reach 90% accuracy, then move to Medium and Hard. Consistency matters more than session length — short daily sessions are more effective than occasional long sessions.
