Hello, I'm Lee Kwang Ho. I've been waiting for this lecture for a long time, so I've been listening to it I have a question about the use of V- you mentioned. Since 8 words of GM7 are IV Maj7, can't we see D7 and Am7 as V7/IV and II-7 for them respectively? If the 7 words Am7 is V-, then the Aeolian scale should be used, but the melody has F#, so I thought it should be Dorian. Is it okay to analyze it in the way I understand it?
