Hi Thomas

Interesting question.

Last time we counted (around July time) there were 233 jazz lessons, 21 blues lessons, and 42 Brazilian lessons.

The total run time of the above lessons was **74 hours, 2 minutes, and 6 seconds.**

There have been many more lessons and courses added since then, but we would need roughly 3 days to watch each video one after another without a break.

### To *absorb* the concepts and ideas in each lesson:

I would estimate it would take 1 to 3 years for a student with previous piano experience to work through the courses and to understand the theoretical underpinnings of the concepts and ideas covered.

### To *master* the concepts and ideas in each lesson:

To master the concepts covered, I feel it’s very difficult/impossible to answer that question.

There are too many variables involved.

I think @LoriNelson answers the question beautifully:

That’s the way I see my own journey with jazz.

I just try to get a little better each day and slowly but surely I am reaching my goals and aspirations.

Hope this helps!
