Basic method (or, if you will, a "chord" with only one "note"):

A "chord" with two "notes":

         (caller)                (caller)
             |                       |

                         |
                 { output(X + Y) }

The specific details differ from what I've written here. In Polyphonic
C#, you don't have to instantiate a chord, you simply start calling
methods, and the runtime matches up complete sets dynamically.

sounds like "Currying" a function but with the parameters taken in any 
order, though, in a sense, perhaps not generating intermediate functions...
