Thanks for pointing that out. I'll fix it, but for now just have the .trane directory in the folder right above. I guess you are right. The textbooks definitely have dependencies, but that seems to be the very problem that you have with them. Unfortunately, I think other than different curriculums for each way to approach the subject, this is beyond the current scope of Trane. I made this thinking of music at first, which has a more rigid way of approaching the subject that tends to work for a wide set of students. There's no person on earth that will be comfortable studying highly chromatic music without mastering harmonically easier material first.
