4th string
D tuning note
When using the basic
tuning method for standard tuning, you would play the 5th
fret on the 4th string and tune the 3rd string open to that.
In Drop D tuning, you are going to play the 7th fret on the
4th string, then tune the 3rd string open to that. From there,
you will tune everything the same as standard tuning. You could
also tune the rest of the strings using harmonics.
