Klang-Spektrum

Klang-Spektrum makes music theory and ear training click for children and teens aged 10 and up, through short, playful exercises that actually stick.

Instead of dry theory, you practise actively: you hear intervals, recognise pitches, play or sing them back, and get instant feedback. Learning to read music turns into a game you enjoy.
