Changing pitch

[Guy Shaviv]

I'm typesetting a piece for classical guitar. The classical guitar's note range 
is from e to g'''. 
Using the default pitch settings of lilypond is cumbersome as you need to 
constantly use ' 
marks. I would like to change the pitch such that c = c'' that is raise the 
meaning of the pitches 
by two octaves. I do not want to use \relative mode as it is not uncommon in 
guitar to have 
music spanning 2 octaves or more in a single bar and I find the relative nature 
of \relative is  
confusing in these cases as you have to contantly use ,, and '' to write such 
music.
