I was listening to part of the master class tutorial and Steve mentioned a song writing tutorial so I was reading the post and it seems to indicate that it may be in the works. However, I am unsure what Logistics are involved. I am unsure of hand what ETA is.
When it comes to theory, the basics would be easy to get. Getting the arrangement to sound good is mostly found by in your ear. There's no right and wrong but understanding what it is you do, what to call it, such as, where the majors and the minors and the diminished and augmented goes diatonically does help. That's not hard to understand if you can spell the chords.
