thanks for sharing this excerpt, i found many things to learn.

but could you please clarify this part of the code? :

    % the 5s are just "a value different from any accidental"
    \set Staff.keySignature = #'((0 . 5) (1 . 5) (2 . 5) (3 . 5)
                                 (4 . 5) (5 . 5) (6 . 5))

i searched Staff.keySignature in the manual and the example is somewhat
different, involving pairs ((octave . step) . alter). i also get lots
of warnings when compiling:

warning: No glyph found for alteration: 5

i found the example in the LSR but without much explanation. i guess
it's a bogus alteration to force naturals appearing before notes
without alteration. could anyone elaborate a bit on how and why this
works?


thanks,

lj
