This book is absolutely wonderful...so much so, it deserves a kiss before I go to bed each night! Seriously, though, this book is well organized, chock-full of information, and can be digested at a rapid pace if you find yourself getting really into it (which is very likely to happen). As one can guess, it starts off with basic info about various vocal ranges. Then, it gets you started on the basics behind note-for-note harmonization for voice, utilizing primary triads only at first, then including secondary triads, diatonic sevenths, and chromatic chords as you desire. It features a chapter on writing material for introductions, endings and interludes, and a very useful chapter on smooth vocal modulations. It also builds up your vocal arranging toolbox by taking you from two-part to four-part arranging, including the various techniques (figuration, ostinato, imitation, vocal background) that you can use with each technique.
It covers a little bit of barbershop technique, and has an entire chapter on jazz vocal harmony, where it discusses the uses of upper extension tones, substitutions, and how to make the most of these. Throw in material dealing with other contemporary styles (pop, rock, country), a chapter on getting arrangements published, and chapters concerning the role of instrumental accompaniment - and you're looking at the holy grail of choral arranging. Whether you want to arrange hymns, showtunes, jazz or pop/rock, this book will be an invaluable aid! It's so well-explained, in fact, that you'll immediately be able to HEAR the logic and techniques behind vocal arrangements that once sounded complex.
Plus, each chapter gives you exercises at the end so you can immediately put theory to practice...and there's no additional workbook to buy - everything you need is included in TWO appendices in the back. One appendix has melodies only (usually of a simple folk/hymnal nature), which are to be used in the assignments. The other appendix has some complete vocal arrangements, to be used for analysis while reading certain chapters.
I hate to be long-winded here, but since this Amazon doesn't have the 'Search Inside' feature with this book, I figured potential buyers may want to know the bounty of information contained in this book before they drop $70-100 on it.
Don't spend half a year eyeballing this book like I did, buy it now!
