What is a short octave piano please?

[Quickquestion]

Hi all
I'm supposed to be playing the piano at my friends wedding on Saturday, she's just told me that it's a short octave piano. Can anyone please tell me if I can still play it? I've searched the internet and can't find any information as to whether this will make any difference to me.
I'd appreciate any help.
Thanks
Jo

Anything less than the usual 85/88 notes. Often 6 octaves, sometimes 5.

Handy for playing the "Wedding March" right hand only.

I know what a short octave is, but I've never heard it applied to pianos. It was common on harpsichords, particularly small harpsichords that weren't tuned to equal temperament. Let's just say that the harpsichord was tuned to sound good in C major, but the lowest note was an F key. That F key would actually be a C, the G would be an E, the A would be a G or something.

I would however speculate that a short octave piano is one with 6 octaves or something, with all the notes tuned as you'd expect.

Thanks for your replies. I guess i'll have to wait until the day and hope it's only missing one or two octaves!
Thanks
