This is a short textbook on an alternative technique for stringing and tuning a guitar to get a very bright, treble-y sound that can be used to create some very unusual effects. It may at least interest some of the people who've asked me questions about Nashville stringing/tuning when I've used it in performance. It includes information on more-or-less related tunings, and the factors that need to be taken into account when considering setting up an electric or acoustic Nashville-strung guitar. It also includes links to a number of sample sound files illustrating the technique and ways in which it can be used to emulate other instruments.
