Another way of notating this, which I prefer, but also I think needs to be  
implemented, is to follow the decresc. (or precede the cresc.) with a  
bold/italic "n" or "n.", for niente.

At least one music font/notation program, I forget which, includes for  
this purpose a letter "n" in the same style as mrsfp for dynamics. So  
perhaps the ideal way to implement this latter kind of niente notation  
(the hairpin circle tip being the other kind) would be to create a new  
dynamic mark, called "n", and syntax analogous to the other dynamics, thus:

c2~\> c~ c r\n

...would do a hairpin decresc. to niente, with the "n" marked under the  
rest (and, like any other dynamic mark, signalling an end of the hairpin).

Perhaps, then, there could be a setting which would decide whether that  
syntax prints a dynamic letter "n" on the one hand, or modifies the  
hairpin with a circle at the tip, on the other hand.

Then one could switch globally between the two methods of notating niente  
without rewriting each instance.

The syntax for a cresc. from silence would have to be a little less  
elegant, though maybe simply:

c2~\n\< c~ c\! r

And for consistency, the first example could be modified to:

c2~\> c~ c r\!\n

...explicitly ending the descrescendo.

I don't know whether this sort of syntax is practical; it's just the first  
thing that comes to mind.

Maybe more practical is 1) a setting to switch on/off circles at the point  
of a hairpin, for the first method of notation, and 2) a new dynamic  
letter, "n" (and command "\n"), for the second method.

As an alternative to the second method -- and a perhaps more conventional  
one, recommended by Kurt Stone -- niente can be notated not with the  
dynamic letter "n" but with the italic "n." (this time with a period).  
This should be possible to do now, but I can't figure out how to switch  
off the boldface:

n = #(make-dynamic-script (markup #:text #:italic "n." ) ) % This makes  
the text bold-italic.

n = #(make-dynamic-script (markup #:text "n." ) ) % In fact, even this  
makes it bold-italic, as if that's the default text font style. Why? And  
how to switch it off?

(I'm using make-dynamic-script, rather than a regular \markup command,  
because the "n." needs to be aligned with the hairpin.)

Thanks in advance for any feedback on the "niente" implementation/syntax  
(I too might be willing to co-sponsor it) and/or on this latter problem of  
bold-italic text.
