Practice identifying musical intervals
An interval describes the distance between two notes. Press Play new question and choose the interval you hear. Replay repeats the same notes, and Stop ends playback. Ascending and descending modes play the notes in sequence; Together plays them at the same time.
Beginner practice includes the major second, major third, perfect fifth and octave. Intermediate adds the minor second, minor third and perfect fourth. Advanced includes all twelve intervals from a minor second to an octave. Each question uses a different randomly chosen starting pitch, so listen for the relationship between notes.
Use feedback to train your ear
Each question accepts one scored answer. The correct choice is highlighted after you answer, and you can replay the sound before continuing. Changing difficulty resets the score. Short, regular listening sessions help you compare intervals without relying on a single starting note.
Using the Interval Ear Trainer
Practice hearing the distance between two notes. Start with the smaller beginner set and add more choices when the differences become easier to recognize.
Instructions
- Choose Difficulty and Playback, then set Volume to a comfortable level.
- Click Play new question, listen to both notes and choose an interval. Replay repeats the same question.
- Read the feedback, then play another question. Stop ends the sound; Reset score starts a fresh score.
Understanding the score
The score counts your first answer to each question. An octave has twelve semitones; a perfect fifth has seven. Ascending and descending modes change the order of the notes, while Together plays both at once, which can make the interval feel different.
What to do if intervals are hard to tell apart
- Use Replay before answering and compare the interval with one you already know. The root pitch changes, so listen for the relationship.
- Return to Beginner if the advanced choices are too similar. Changing Difficulty resets the score.
- If no sound plays, check your output device and Volume, then press Play new question again.
Keep sessions short enough to listen carefully. These synthesized examples train interval recognition, but real recordings can include other instruments and notes at the same time.
