Tonelight

What Tonelight is

Tonelight is a web app for functional ear training: learning how notes function within a key. Its short, game-like practice is designed for about ten minutes a day, and the app tracks areas of strength and difficulty before moving learners to the next level. Exercises cover single pitches, melodies, harmonic intervals, chords, progressions, inversions, sight singing, and contextual hearing through fill-in-the-blank prompts. The curriculum starts with identifying the tonic and adding notes from its triad, then moves into minor tonality, chromatic tones, chords, progressions, and inversions. Beginners can begin at the start, while more serious musicians can jump to units that address their gaps. The free tier includes eight exercises each day and Unit 1, which is available without an account. A free account unlocks Unit 2 and keeps progress. Pro monthly costs $4.99 a month, and Pro yearly costs $39 a year. Both plans provide unlimited daily exercises, the full curriculum, sight-singing mode with pitch detection, and progress tracking across devices. Pro can be canceled from the account page, with access lasting until the current billing period ends.
