Piano Theory Courses

Question: Is there a book or a course for sale because I'm guessing the free lessons are probably very basic and don't cover everything mentioned above.

Albert's reply: Yes, comprehensive courses at all levels are currently in development! There will be some very effective tools. I recommend subscribing to our mailing list or RSS feed so you'll learn of the courses as soon as they're available. (e-zine subscribers will also receive discount offers.)
