My own experience of the course has been extremely positive. As a beginner to intermediate level player, I find the lessons stimulating and challenging, taking me on average about two weeks each to complete to a sufficient level of proficiency to enable progression. They are very well structured with each lesson building on the last and offering fresh challenges. The course has already enabled me to uncover various issues with my technique that I was unaware of and has provided to clear roadmap as to how to address them. In addition, my appreciation of musical theory is progressing steadily. In summary, this is an excellent, well-organized, practically useful course that is well worth its relatively modest cost.
