Grade 3 is a step up and I'm finding it a lot more challenging, but the videos are very good and easy to navigate and repeat to look again at the more difficult areas to learn. You have an excellent set up and it's good value. Ian

I have just been looking over your modern song composition guide. This is really excellent. I like how it is so comprehensive yet succinct and giving so much useful detail. It demystifies modern song writing for me as I am currently only familiar with classical music theory. I look forward to getting this knowledge under my belt and using it in my compositions. Bernice

I’ve bought the books at Grades 6, 7 and 8. Although I’m not taking the exams, I’m finding the books very useful, with their clarity, worked examples, etc. I have recommended them on the Tonebase website of which I am a member.

Thank you so much. I am so grateful to have discovered your program! So much more informative than the other book series. I am learning the material much better and faster now, thanks to your program.

Just a short email to say that I passed grade 8 theory. This has been a long road, but a very satisfying one – I started learning music theory almost exclusively with your website way back in 2011. There is no way I could have passed these exams without your help and teachings. Thank you so very much. Once I passed grade 5 theory, I decided to change careers to being a media composer (and I still am one to this day). You’re changing lives. Thank you so much.
