Hi, Robbie.  Okay, I'll take a stab at it.  But, remember, we're talking
about "art" here, so everything is subjective.

First to mind is the use of dynamics (in regard to both tempo and
volume).  I feel that dramatic changes, such as ending crescendos, 
might work better for large audiences.  Also, endings that slow down,
might seem tedious after a while for the single listener.

(I might be confusing two considerations here: there is first the _size_
of the audience, then there is also the _turnover_ of the audience.  
The larger music boxes -- the coin-operated ones come to mind -- are
generally not listened to over and over by the same persons, while a
small, jewelry movement would be listened to many times by the same
person).

Also, with the single listener, there is less likely to be ambient noise
around, so that would allow for 'thinner, more delicate' obbligato grace
lines.  I find that, with the larger disc machines, I usually need to
double (in octaves or fifths, most often) the grace lines so that they
can be heard in balance by a large group.

There are probably a lot more specific techniques I could mention, but
I'm probably already boring your readers, so I'll just end with what I
think is a pretty good analogy:  Think of a speaker delivering a speech
to a large group. (Or, a television announcer or news anchor-person.)
Now, imagine how strange it would seem if that person came into your
living room, sat down with you on your sofa, and began speaking to you
with that same delivery and tone of voice!

Best,¶
