Is putting the name of the application in quotes a convention used throughout this guide? It's an unusual use of quotation marks and I don't think it's necessary to highlight the name of the application throughout the document anyway. My main problem with this is that in several places the application name is used in the possessive, which is definitely not a correct use of quotes and it makes it somewhat awkward to read. If you feel the quotes are necessary, may I suggest avoiding the possessive? For instance:
"Solfege"'s exercises are arranged in six broad categories
could be changed to
The exercises in "Solfege" are arranged in six broad categories

Also, now that I look at it, the Exercise Types section talks about the six broad categories but goes on to list thirteen items, which don't seem very broad. Not having used this program I don't really know what should go here.
