Interval comparison
Span - interval comparison ear training game
Span trains interval size perception without asking you to name every interval immediately.
What this game trains
Intervals
Some listening skills are comparative before they are verbal. Span helps you feel which interval is wider, which is a powerful bridge toward naming intervals, transcribing melodies, and hearing melodic contour.
How it works
Coco keeps each question focused and scores the listening task immediately.
- Hear a small set of intervals in sequence.
- Choose which one spans the widest distance.
- Use comparison instead of memorized labels.
- Progress into closer intervals and mixed presentations.
Difficulty progression
Levels add musical material gradually so the challenge grows with your ear.
- Starts with large differences between interval sizes.
- Adds closer distractors that require sharper comparison.
- Uses faster decisions once size perception becomes reliable.

FAQ
Common questions
Can beginners use this game?
Yes. Early levels keep the answer set narrow, then add more notes, intervals, chords, or scales as your ear gets stronger.
Why compare intervals instead of naming them?
Comparison trains raw distance perception. Naming gets easier when your ear already understands which sound is larger or smaller.
