excellent! i am sick of 4/4 and the like!!! heard of the dave bruebeck quartet? two albums to note, "time out" and "time further out"....off hand the only track i can think of in 9/8 is "blue shadow in the street" from time further out.....joe morello is awesome in strange time signatures.....the other thing you could do is a division of signatures, like matt cameron from soundgarden did when they covered into the void...ie; split the signature (into the void is 7/4, and matt plays a distinctive 3/4, 4/4 split)...........perhaps a 5/4-4/4 split would do the trick?...my old band used to mess with signatures alot, i used to just catch the riff, or the accents of the chords, keep the hats going and then make sure there wasw either a snare or a bass drum meeting the accents......another way to do it, is fake it (kinda) when a signature completely had me lost, i would tell the guitarist to keep playing no matter what i did, so say for instance this particular song called for a swinging 5/4 (i hate playing 5/4) what i would do is play a shuffly 4/4 beat at the same bpm and every five or six bars we would hit the same accents.....if you can pull this off its is more enjoyable than playing the correct signature, i beleive this is known as a polyryhtm, and some pianists do it by playing thier left hand at one sig. and their right at another... i think bill bruford is an excellent player of polyrythms, but i dare say he planned his, and didn't use them as cop outs......
now i must not my old band was an instrumental jazz/prog rock band so being instrumental, we had plenty of room to move arouund and cut bits out live if they weren't working, but if this song is structured and set in stone, you may have a little trouble working out verse length if you go the polyrythm option.....
by now i am sure your eyes are tired, so i will let you get to it, the options for time signatures is virtually endless, its just that music society is stuck wtih 4/4 because there are alot of lazy musicians, especially drummers out there (not all, but most)
