I hate to argue semantics, but:
According to the Oxford Dictionary: im•promptu adj.
done without preparation or planning improvised: an impromptu speech They often held impromptu meetings in their house.
with the key, as far as magic is concerned, is
without preparation. Robin Williams' definition of improvisation does not apply here.
Improvisation, again from Oxford:
1 to make or do sth using whatever is available, usually because you do not have what you really need: [v] There isn’t much equipment. We’re going to have to improvise. [vn] We improvised some shelves out of planks of wood and bricks.
2 ~ (on sth) to invent music, the words in a play, a statement, etc. while you are playing or speaking, instead of planning it in advance: [v] ‘It’ll be ready some time next week, I expect,’ she said, improvising. He improvised on the melody. [vn] an improvised speech
Improvisation, basically, means to make it up as you go along, although, as Robin Williams pointed out, many "improvs" can be planned.
So, back to magic,
Impromptu, from the magic sense means that there is no pre-arrangement or special equipment needed and that any stacking (for cards) or any other secret preparation are done while the effect is being performed.
A prefect example if the levitation effect using two folding chairs (where the person is laid across two chairs, on at the head the other at the feet, and then the chair at the feet is removed leaving the person floating balanced on the one chair, defying all known lays of physics) . If you are someplace that happens to have two folding chairs this effect could
appear impromptu, but I do not believe that I am guilty of any sort of exposure by stating that it there was some advanced preparation, and therefore the effect is not impromptu.
So, as it applied to an effect "impromptu" is defined from the point of view of the magician, not the audience.
The Queen of Clubs is correct.
