ok. Do you think it should return a string or is an int fine. I clefs
names are stored in an enum. I think I would have to write a function to
return a string value. I saw that you wrote a define in denemo_types.h
but this is for an array. Should I write an array and have the value
looked up by the inter value corresponding with the enum clef value? Or
should I just have the function return an int. 

Thanks,
