The Harmony Games course is based on an understanding of a common concept for a range of chord progressions which is new for me and this understanding is interesting for me to come into. This is good and possible for me to handle in the first parts. However, I realise that I need some weeks to get the whole concept under my skin. It is kind of a meditation. I would have appreciated that you had included the notes of the small licks and thrills Adam is using and then I would have been able to learn from this too. I have given a score of 8 because I like the course, but I do not have any friends or colleagus interested in this topic. So the true answer is that I would not recommend it to anyone meaning zero score.
