Hi HP,
It's quite possible that I am not understanding correctly what you are explaining in the lesson but I am referring to the formulas in the article where you show how to add the notes to the minor pentatonic scale to form the different modes of the minor scale:
1:21 Minor Pentatonic 1 2 b3 4 5 b7
7:10 Aeolian 1 2 b3 4 5 b6 b7
9:02 Dorian 1 2 b3 4 5 6 b7
10:40 Phyrgian 1 b2 b3 4 5 b6 b7
Shouldn't 1 2 b3 4 5 b7
be 1 b3 4 5 b7 because there is no 2nd in the minor pentatonic scale? I apologize if I am mistaken here but this is just not making sense to me.
Regards
