I know you mentioned this on this particular lesson but yes, how long should I stay on the Ionan+Dorian before moving to Myxolidian? Also, just to confirm, learn the notes of Dorian with the same approach as the ear training for C Major scale, correct?
Here is Tomo's reply:
"Thanks so much for subscribing to my Guitar Wisdom. This is a good question! Keep it very simple. Start with one finger on one string. You can work on Ionian and Mixolydian, too. I think it's good to work on the b3 b7 scale first. Then, go to the b7 scale. Take your time. Try a few different keys."
