If in doubt about the syntax of a music expression, take a look at
ly/music-functions-init.ly : 

  tag = 
  #(define-music-function (parser location tag arg) (symbol? ly:music?)
     "Add @var{tag} to the @code{tags} property of @var{arg}."

the (symbol? ly:music?) part tells you the number and type of
arguments. Also check the argument names (here: tag and arg). When they
are well chosen, they should be self explaining.
