Hi,
I saw your post last night but it was to late.
Just to make it clear, I think too that first post on this exercise sound pretty well. The Dm7/C7 measure sounded to me dissonant without melody.
After you explained to me what to do i think now is better.
(bad English, me Tarzan
)
P.S.
Could you please install Finale Notepad (it's free) so I could post you Only *.mus file? this could make working easier, I think.
