Thats true although I read the question as meaning can I pass in an
arbitrary list of arguments even though the function takes 3... The
follow-on question seemed to back up that understanding. But it
could mean what you took it for in which case clearly the answer
is yes and *chords would have worked.

I cobfess I don;t like the *args style where the function takes a 
specified
number of params because I find it too easy to hide bugs by 
inadvertantly
passing the wrong number of args. Explicit is better etc...
