This question was sent by Lev, and he writes:\n \nHello Vidas,\n\nCould you please (if you find time) take a look at my suggestions for progression T1TS2SD3DT4T in C major and a minor (Exercise 9-2 from Harmony for organists course) and give me short feedback about mistakes. I'd like to make sure I've understood the harmony stuff correctly so far.\n\nThanks in advance and best regards
