I have recently been trying to hone in my improvisational skills. I'm stuck in the first position of the Am pentatonic box and can't move away from it. Whenever I try to move out of it, I randomize the next box that I go to, which most of the time leads to bad sounding improvisations.

I have narrowed the problem down to it being me having a bad sense of rhythm. I think I've got technique as a rhythm guitarist, but in regards to musicality, I don't. 

I don't know which chords go together well, what goes after a chord, how minors, majors and 7ths are formed (don't know if this is important to be a good rhythm guitarist though), etc.


Question: Is it ethical to profit by having my students buy my textbook?
Answer: One arrangement with the publisher of my two "text"-books was that the price be reduced by the amount of the otherwise-royalty for any books sold through the university bookstore, so that, in effect, I was not collecting royalties from students at this university (whether or not I was the instructor).

Another aspect is making printouts from PDFs available at-cost to students at this university, which is what my contract with the publisher specifically allowed in one case.
