I'd like to set fingeringOrientations once for the whole \book.

[list_lilypond]

In a book with guitar music I'd like to position the fingering numbers  
at the left sides of the notes.

I already found out that notes have to be written as chords, i.e.  
<a'>, and tried to put
\set fingeringOrientations = #('left') in the layout block, which didn't work.
Then tried the \score block, which didn't work either.

It is as if I can only set the fingering orientations inside every  
newly created staff throughout the whole book.

Is this true, or did I just not find out how to do it properly?


Thanks.
