Very good material. But I think there are some minor mistakes in lesson 6 chord progression. At the bottom, you wrote:
| Tonic | Subdominant | Dominant |
|---|---|---|
| C D# F# A | C# E G A# | C D# F# A |
I think the right one should be like this (subdominant and dominant):
| Tonic | Subdominant | Dominant | |||
|---|---|---|---|---|---|
| Primary | Secondary | Primary | Secondary | Primary | Secondary |
| C, F♯ | A, D♯ | F, B | D, G♯ | G, C♯ | E, A♯ |
According to Wikipedia: Axis system - Wikipedia
There are minor mistakes in other lessons, but so far I have found, this is the biggest one.
I really want to download some of your game cart of this tutorial, please tell me how if possible.
