In standard tuning
...the keys having the most open strings on simple harmonic patterns are: -
E A D G and C
However, due to problems in orchestration coupled with vocal ranges, these keys are often unavailable.
Therefore, wherever solo passages are not too rangy, ten additional "open string" keys are available by tuning the entire guitar up or down one half tone.
Tuning down one half tone produces "open string" keys :-
Eb Ab Db Gb and B
Tuning up one half tone produces "open string" keys :-
F Bb Eb Ab and Db
