Tune at the beginning of "Territory"

"Territory"[1] is a short story or novellette by Poul Anderson.
I have it in the collection _Trader to the Stars_. At the beginning,
there is written a short musical passage: two dotted whole notes,
four slurred 32-nd notes, followed by two more dotted whole notes.
Does anybody here know what this tune is? I think that it is actually
relevant to the story, since the 32-nd notes are marked "gliss." and
the word "glissandos" is used on the same page (fifth paragraph).
I realize that my description isn't enough to identify the tune,
but if somebody musically inclined has a copy of "Territory", they
could look at it and play it on a piano or violin or something. If
they wanted to do so.
