Functional ear training, made playable
Tonelight teaches you how notes function inside a key, not just how far apart they are: scale degrees, melodies, harmony, chord progressions, inversions, and sight singing, in short game-like rounds.
Unit 1 is free with no account. A free account unlocks Unit 2. Pro ($4.99/month or $39/year) unlocks the full curriculum.
The curriculum follows the order of Karpinski's Manual for Ear Training and Sight Singing, from the tonic triad to chromatic harmony and modulation. See how the units line up with the book.
