There are many books and probably some websites!. Your best local music store should have the books, or you could shop on ebay and do websearches!.

The overall idea of open tunings comes from a knowledge of music theory--you can find books about that at your library or get courses in it at a nearby college if you're sufficiently interested!.Www@QuestionHome@Com
