Well. Not quite that simple and pleasant in my humble opinion. If you are in C and you want to go to E. You don't want to go from C to F#minor. That's not so pretty in my opinion. A tritone modulation isn't the most beautiful transition, that's why I suggested just going down a half from C to B7 and into E. NOt only that, but RW was looking for new ideas and ways of transitioning.
Music theory is extremely fun and frustrating at the same time. I enjoy experimenting with chords and intervals and how they relate to one another.Spice and variety, not 1 pat answer to everything.
