Hack Music Theory is a music education project founded by Kate and Ray Harmony, now based in Canada. The site emphasizes “100% Human. 0% AI.” and focuses on teaching music theory, composition, and music production through real instructors with professional backgrounds. The content mentioned includes books, courses, tutorials, free books, free PDFs, and articles, alongside the Hack Music Theory YouTube channel.
Its course areas center on music theory, composition, songwriting, and methodologies for making music. Unlike broad entertainment-oriented music channels, this project places more emphasis on a systematic understanding of music theory and on applying theory to creation. In terms of delivery format, the main text does not clearly state whether the courses are live, recorded, or one-on-one, nor does it provide a specific schedule, lesson length, or learning path. We can only confirm that it offers books, courses, tutorials, and YouTube content. No certification or certificate information is disclosed, so it should not be treated as a professional certification program.
The strongest point is its instructor background. Ray Harmony is introduced as a music lecturer with around 30 years of teaching experience. He reportedly taught music theory and composition at West London College for about 10 years and held roles such as course director. He also has educational experience with institutions such as the Royal Schools of Music and Musicians Institute, as well as music production experience working with Grammy winners and multi-platinum artists. This gives the project relatively strong credibility across three areas: understanding theory, understanding creation, and knowing how to teach.
The main text only clearly states that subscribing to Ray’s Substack gives access to a free short book that can be read in about 30 minutes. Beyond that, prices for paid courses or books, subscription fees, refund policies, and payment methods are not disclosed. Users planning to study systematically will still need to visit the specific purchase pages to verify costs and included benefits.
The advantages are a relatively complete instructor profile, plus free books, free PDFs, articles, and YouTube tutorials, making it suitable for low-cost trial learning. Its philosophy also clearly positions itself against AI misinformation and “fake experts.” The drawbacks are that the site’s main content provides limited detail about the course products themselves, lacking key purchase information such as syllabi, delivery format, pricing, certificates, and learner support. In addition, the page content is in English, so Chinese learners with limited English listening or reading ability may face a higher learning barrier.
It is better suited to self-learners who want to study music theory, composition fundamentals, and songwriting thinking, especially those who feel confused by traditional theory teaching and want to use free materials to judge the instructor’s style first. It is not ideal for users who specifically need Chinese-language instruction, professional certificates, fixed cohort classes, or one-on-one coaching. The main text does not provide information on access from mainland China. Network connectivity, payment methods, and the availability of YouTube/Substack should be tested independently. If access is restricted, alternatives include public courses from Chinese music conservatories, music theory courses on Bilibili, or Music Matters as an English-language alternative mentioned in the source text.
