Well, what's wrong is the version.

    Parser: properly disambiguate pitches from music in function arguments
    
    In many instances, function arguments were parsed greedily without
    looking at the function argument predicates first.  This did not allow
    using subsequent function arguments of type pitch and duration since
    they were combined into one music expression.

Embarrassingly without issue number.  But the corresponding version
appears to be 2.19.0.

So just use the latest stable prerelease (2.19.81 right now, but I have
put 2.19.82 in the queue and it might surface some time next week or
so).
