Resonanzplatte
Identify the distance between two synthesized tones, then inspect where your ears disagree.
A casual ear-training exercise—not a hearing test, grade, or absolute-pitch assessment.

Play one neutral tone and adjust your device volume yourself. This page never raises system volume.
Global sound is muted.
How this training works
Listen to two sequential tones or one simultaneous pair. Mark confidence, identify the interval, and use the comparison corridor after a miss. Root notes and registers vary so you learn relative distance instead of one fixed frequency.
Controls
Space replays. 1 or 2 marks confidence; after that, number keys choose visible answers. Enter advances. P or Escape pauses.
Sound and privacy
Every sound is synthesized in your browser with Web Audio. There are no recordings, song excerpts, background music, microphone requests, or audio uploads.
