emusic theory

just found a site that is interactive, although you have to check settings sometimes or it won't work properly.

www.emusictheory.com/drillChordFunctions.html
www.emusictheory.com/interactChords.html

for some reason, on the chord functions, it sometimes won't let you put in the root of the chord.  maybe something's wrong with this site?  also i clicked augmented chords and i ended up doing root position chords.  this site kinda messes with your mind - unless i'm missing something.
