Every lesson will have two main areas for you. Each of these will have more to study if you want it. Every song we sing has two parts, words and music:
Making sentences out of words is like making the music for a song.
But which comes first?
That is why it is good for you to learn both together. OK...sometimes you'll work on one side more than the other. That's all right. Go as deep on either side as you want.
