Whenever a guitarist wants to learn an alternate tuning, the practical details are easily addressed (string-guage, using a tuner). But the strategic aspect cannot be gained without many Saturday nights spent in the shed. Or can it?
What's the most useful alternate tuning and why? Please give a detailed explanation focused on one particular tuning. Example songs making use of the tuning would be great.
