198 different (5, 6, 7, 8, 9, & 10 tone) musical scales from around the world -- cross referenced to 95 ethnic and regional usages. Listed by intervals, relation to the Major Scale, separate tone groups, and relations to other scales. Written at a level for even beginning music lovers but going into depths -- cycling the intervals of modes -- even cycling scale intervals in retrograde inversion, and other interesting ways. Shows how to change scales by changing the number or type of tones. It started as a game and just grew!
198 different scales given numbers by their relation to the Major Scale (the Major being #1) and are then listed in various way: by number, by intervals, by their first tetrachord, by their alternate symbols (is that a C sharp or a D flat? both ways are there), etc. Then they are put into retrograde-inversions, modal series, and any other way I could think of (I had so much fun!). There is a section strictly on the 167 scales for which I was able to find an ethnic use. In this section I list the ethnic scales both by the countries-with-scales and scales-with-countries and in other interesting ways. There is a section on the diantonic modes. But the gem of this book is what I call "The Grand Finale". Each scale is there (in numberical order) with all of the information I was able to collect on it and includes a staff-with-notes (based on the Major Scale in the key of C).
There is an outline of the Table of Contents, and then an exhaustive Table of Contents. At the back there is an exhaustive Index. It is referenced and cross-referenced. This book actually is easy to understand and can be easily enjoyed by anyone with a mere rudimentary knowledge of music. Yes, technically it would be called a reference book, but I think of it as my book of scale games. (I copyrighted this as "Margaret J. Chamberlain". The "J" stands for "Joelee", the name I actually go by.)
