looking for feedback from beginers

hey all,
ive been working on a book for beginers to help them start to understand a bit more about music theory. I figure while im working on the next section maybe i could get some input on the first few i have done. Keep in mind this hasnt been edited so if any of you that are more advanced would like to point out any mistakes i might have made that would be great. there are also midi files to go along with some of the examples to help make note duration more understandable. its a free download all i ask is for a bit of feed back..thanks heres the download http://www.mikefly.com/imt.zip
and its a work book so make sure you do the lessons and i have the awnser keys that i will post in a week or so

btw to the staff at GN great forum and i hope im not breaking any rules by doing this
