Most likely: the language needs to be put in quotes:

\language "myLanguage"

Better to put the langauge definition into a separate .ly-file and include it.
Production code should also check whether the language is already defined, 
otherwise 
language-pitch-names will grow.
Something like this (save it in a file called myLanguage.ly):

#(let ((new-lang 
       `(myLanguage . ((ceses . ,(ly:make-pitch -1 0 DOUBLE-FLAT))))))
  
  (if (not (assoc 'myLanguage language-pitch-names))
      (set! language-pitch-names (cons  new-lang language-pitch-names))))

\language "myLanguage"


If you put this file somewhere where lilypond searches for includes and add
\inlcude "myLanguage.ly" to your file.
