Made famous by the legendary Jerry Byrd, the C6 tuning [CEGACE] for the non-pedal lap steel guitar has many advantages due to its versatility. The tuning is especially useful in playing two and three-string chord combinations and for easy single-string passages. Patience, dedication and many hours of practice are needed to perfect the "slant" bar positions, especially the reverse slants, but the end result is well worth the effort. This excellent text, written by Steel Guitar and Country Music Hall of Fame member DeWitt Scott, is written in standard notation and tablature. Includes access to online audio.
I'm only at the beginning of the book, but it is very good. I'm a musician and know reading and theory, so I don't know how this book will be for a complete newbie. But for one who know the basics and want to learn really unique instrument this book is very helpful. By the way, it isn't even similar to guitar.
