Music Theory Learning with Spaced Repetition Games

Most people struggle to retain music theory because traditional courses are boring and knowledge fades quickly. This gamified course uses interactive lessons and spaced repetition to teach music theory from basics through advanced concepts like Secondary Dominants. Target users are aspiring musicians, producers, and music students.

Duolingo's rise and the broader EdTech shift toward retention-science-backed learning have primed users to expect spaced repetition in skill acquisition, and music theory remains genuinely underserved compared to language learning or coding. Tonestarter and a handful of Anki deck collections exist, but there's no clear incumbent that combines interactive ear training, theory, and SRS in a polished consumer product. The $2k–$10k/mo band is plausible for a solo founder via a freemium or low-priced subscription, though it requires meaningful retention numbers to offset the naturally small addressable market — serious learners who stick with music theory long enough to pay. The biggest risk is that the motivated subset of musicians willing to grind spaced repetition is simply too small to grow beyond a few hundred subscribers, leaving the product stranded in a niche that feels larger than it is.
