Hm, it requires a default-value. Why do I need to use it?

It's because a music function needs a specific type as a signature, so
it has to be either a string or a markup :-(

I'm afraid it would require a new C++ underlying paradigm, such as
ly:make-attached-objet or whatever.

I do intend to implement it as soon as I'm able to.
Within a dozen years or so.
