Introduction and Table of Contents

So there you are... walking along, when suddenly you come to a big wall... and written all over it are ideas... ideas for songwriters.

Along the way, most songwriters have some questions. Many of the questions have easy answers, but sometimes you meet one that looks like a mountain in your path.

One of the biggest mountains can be described this way. Let's say we're writing a song. First we choose a key. Now here comes the mountain. Which chords are available in this key... and how do they flow from one to another in ways that sound good?

These questions are very easy to ask, but it took me years to understand what I wanted to know. Now I can explain some of what seemed mysterious to me then. If you are asking questions like these, this web site may help you to understand more quickly. Have fun!
