Engineering Sandbox practice ยท teoria drills

Hear the interval, then name the distance between the notes.

This drill keeps the original Teoria runtime intact, but reframes the page around one job: listen, compare the two notes, and lock in the interval quality before you answer.

How to use this page

Start the exercise first, replay the prompt until the distance feels stable, then answer before peeking at the score. If you get stuck, switch answer modes and compare what the keyboard and notation views are telling you.

Quick start

  1. 1
    Start playbackWait for the local piano bank to finish preloading, then trigger the first prompt.
  2. 2
    Judge the intervalListen for the distance and direction before deciding on the label.
  3. 3
    Check your streakUse the score panel to see whether your ear is stabilizing or still wobbling.
Why this drill matters

Compare the two pitches before answering: interval number counts letter-name steps, while quality distinguishes sizes such as major and minor. After an error, replay and compare again. The score records these attempts, not overall musical ability.

Listen: replay the pair before answering. Compare: use the keyboard view when the label feels fuzzy. Track: score changes after every response.
