Noteflight is a popular online music notation application that provides both a free version as well as an enhanced subscription product.  Their Crescendo version of Noteflight is popular with schools as it opens up a lot of additional capabilities including the feature of allowing the teacher to post and accept assignments from their students.  Now it appears that Noteflight has begun to reach out to publishers, specifcally the publisher of the popular Musician's Guide To Theory and Analysis, and created an online compliment to the text intended to tutor students though the process of learning music theory. 

From the Noteflight press release:  

Noteflight LLC announced today the availability of the online interactive version of the student workbook for W.W. Norton’s popular college text, The Musician’s Guide to Theory and Analysis.
