Staff order for nonstandard ensembles

[Patrick O'Keefe]

There are well established standards for staff order for "normal" ensembles but I'm writing a piece a somewhat unusual ensemble: vibraphone, bassoon, and unpitched percussion.   I'm not sure that anybody is going to look at the "full score" but I would like to have it in reasonable shape, just in case.

The default order in my notation software - based on the orchestral order - is bassoon, unpitched percussion, vibraphone.  At the very least, I think the vibraphone and bassoon should be reversed so that the higher range instrument is on top.  Should the percussion be on the bottom?  (That's where I want to put it.)

[Michel.R.E]

normally, stick to the usual order of instruments, so bassoon at the top, the percussion below, tuned percussion highest, untuned percussion below, set each group of percussion by highest to lowest sounding.

in other words:

bassoon
vibraphone
unpitched percussion (from highest to lowest: triangle, woodblocks, that sort of thing at the top, bongos, drums, bass drums at the bottom)
