Learn

If you guess wrong, the correct answer is shown. Over time, your ear will learn to recognize each interval.

What Is an Interval?

An interval is the distance in pitch between two notes, measured in half steps (the smallest step on a piano — one key to the next). Each interval has a unique sound quality that you can learn to recognize by ear.

C D E F G A B Perfect 5th (7 half steps)

Interval Reference

Each interval has a characteristic sound. Associating intervals with famous melodies can help you remember them.

Interval Half Steps Sound Quality Song Reference
Unison0Same note
Minor 2nd1Tense, close"Jaws" theme
Major 2nd2Bright step"Happy Birthday" (first two notes)

Direction Modes

The game offers three ways to hear each interval:

Ascending

Low note first, then high note. The most common way to practice.

Descending

High note first, then low note. Intervals can sound different going down.

Harmonic

Both notes played together. Focuses on the blended sound.

Tip: Start with ascending intervals. Once comfortable, try descending — it's like hearing the melody backwards and requires a different listening skill.

Difficulty Levels

Beginner

  • Unison, Perfect 4th, Perfect 5th, Octave
  • Wide, distinctive intervals
  • Easiest to tell apart

Intermediate

  • Adds 2nds, 3rds, and Tritone
  • 9 intervals total
  • Requires finer listening

Advanced

  • All 13 intervals (adds 6ths and 7ths)
  • Close intervals are challenging
  • Full chromatic ear training

Tips for Success

  • Sing the interval — after hearing it, try to sing both notes. This engages your musical memory.
  • Use song references — associate each interval with a familiar melody. This is the fastest way to learn.
  • Compare similar intervals — major vs minor 3rd, or perfect 4th vs perfect 5th. Learn to hear the difference between close pairs.
  • Practice daily — even 5 minutes a day builds ear training skills steadily.
  • Try all three directions — ascending, descending, and harmonic all develop different aspects of your ear.
