Frank Foxx is a semi-professional guitar player and part-time guitar teacher who plays exclusively in the tuning of open-D. He has written a guitar method book, extolling the virtues of what he considers to be the most versatile and easiest of all guitar tunings, entitled Guitar-eze A Simpler Approach to Playing the Guitar. His website and blog are dedicated to helping aspiring guitarists learn to play guitar.

Open-D tuning is a wonderful, but sadly under-utilized way to play guitar.  For the intuitive, experimenting, or "ear" player, there is no finer tuning to explore guitar, in any musical style.
