When we do gigs and any other performances, trumpets stand in the back row, trombones sit on stools (stand for solos), and saxes sit in chairs in front row and stand for solos. I always stand for solos and sometimes, when saxophones or trombones have soli's or parts just for the section, the whole row stands. That's a good time. The director calls the shots when it comes to where we stand and sit, but in performance, we always stand for solos.

Whenever we rehearse or go to a gig, this is our setup (from left to right from the audience point of view) 1st Row: Tenor 1, Alto 1, Alto 2, Tenor 2, Bari 2nd Row: Trombone 2, Trombone 1, Trombone 3, Bass Trombone 3rd Row: I'm not sure, but I think the Trumpets go 1, 2, 2, 3, 4 Piano, Bass, Drumset, and Guitarist to the left of winds. But the sax's sit, trombones are usually standing, and then the trumpets get a platform to stand on. If we have more than a 16 measure solo, (Our usual is 32 measures+) we stand in our spots, usually there are 2-3 mikes set around the band, and our instructor would place it about a little more than half a foot away from the soloist (At least for me that is, my P. Mauriat Bari with an Otto Link metal mpc and Vandorean ZZ reeds cut through no matter what.) Any soli's the band may have the whole section stands. -BariSaxMan
