Watch the Alt. Standard Tuning online guitar lesson by Andy Aledort from Slide Guitar Power

In this tuning, all of the strings are tuned normal (in standard) except for the G string, which is tuned up one half step to G#, resulting in this tuning (low to high): E A D G# B E. In this tuning, one can lay the slide across the top three strings at any given fret and attain the sound of a major triad.
