If it's okay, I'd like to inform the forum readership of the launch of www.fretboardtopologies.com, official download site for my book, Fretboard Topologies, a catalog of 1,117 scales and modes for guitar players. This book accounts for every possible 5-, 6-, and 7-note scale containing intervals no larger than a major third. It also includes a selection of 8-note scales. Distribution of this book is on the shareware model, i.e., you pay as much or as little as you want, if you want, or you just keep it for free, no strings attached. Please visit the website, download a copy, and let me know what you think, either here or through the Contact function at the site. Thanks! N. Puryear
