(this does assume that we can clone people to play all of the instruments they listed :-) )
Wind section :
1 Bass Clarinet
Percussion / other :
1 Steel pans
Well, that's almost as bad as the proportions of the high school band we had. At its peak, there were 10-14 flutes, up to 10 clarinets, and one or two lonely-looking violinists and maybe a cello. We did have a good range of brass (trumpets, trombones, french horns), and a decent percussion section (drummer, marimba, xylophone). I was one of the flute section, trying not to stand out too much (difficult, being male (most were female), tall (most weren't), and sometimes playing piccolo).
(one day, I'll buy myself a shiny new flute and have a nice quiet place to practice (where no-one can hear me !) and get back in to it. And an alto flute, because they sound nice. And maybe a bass flute, because they're unusual. And a piccolo, just to complete the set. And maybe a nice baroque or renaissance flute, so I can join in with any mediaeval groups around. </dreaming> )
