This Mel Bay Qwikguide begins with basic music theory about scales and keys and teaches how to transpose several songs with and without the capo. Then we look at chords in keys and explore some typical chord progressions by swapping numbers (one, four, five) for the chord names (D, G, A). Finally we study the Nashville Numbering System in depth by examining different notation styles and converting several well-known songs to number charts. The more advanced number charts show detailed arrangements with modulations, intros, extros, a variety of chords, repeats, fermatas, strum patterns, beat accents, and much more. If you're interested in why the capo works as it does; if you're a songwriter or gigging musician who needs to know how to read, write, and understand Nashville Number charts, this book is for you!
