Pick a root note and a scale. Guide dots show exactly which keys to play — follow them in order to build visual and muscle memory. Preview the scale before you start, then jump straight into another round with "One More" or "Another Scale" when you finish.
QUIZ MODE
Listen to a scale and pick the correct name from four choices. Questions play automatically, so you can train your ear at a steady rhythm.
FREE PLAY MODE
Play a two-octave keyboard freely. Scale notes stay highlighted so you can explore melodies and hear how each scale feels.
