Rather, you need to put your code into an engraver.  You then "consist" the engraver to a context.   You can't get at it within your function.  (You may be able to do something with \applyContext, but I didn't have any luck when I tinkered around with this.)

 

I just had a go at it and am running into problems left and right. If I
call (myrootpitch (ly:context-property somecontext 'tonic)) I need a
context as input. The usual context names (like Staff) don't work. The
original function got the context from the ly:translator-context
function. This one, however, requires a translator object as input. In
the documentation, I haven't found a proper explanation what exactly
constitutes a translator object.

The context is easily available to a Scheme engraver, either through ly:translator-context (as here) or as a parameter of the engraver definition:

#(define myEngraver

   (lambda (context)

     (make-engraver

[...]

Hope this helps.
