Before every gig I run my new tracks through this key detector and note the Camelot value for each one. Harmonic mixing is suddenly easy, and my transitions stay in tune instead of clashing. I used to trust messy metadata and guess. Now I know the real key of every song before I touch the decks.

It checks their ear-training answers instantly. Lessons feel practical and fun, and the concepts finally stick because they can hear them in real music.
