Trainspotting

I took my kids to Musee Mechanique today, "one of the world’s largest privately owned collections of mechanically operated musical instruments and antique arcade machines". Jukeboxes are cool! Also, they have dioramas in a range of sizes and degrees of complexity - some really crude and some rather fancy and elaborate, with many characters and scenes. There was a diorama of a fair, with shooting gallery, an acrobat, concession stands, freak show, Ferris wheel, and a brass band. I snapped it with my phone.



The quality is regrettable, but still you can see: four clarinetists on the left of the conductor, four trumpets - notably, not cornets - on the right (only three are visible in the pic), then in the back row - flute, snare drum, bass drum, sousaphone, euphonium, tuba, two trombones, and in the middle no less than three mellophone players! These are not French horns, since they are played with right hand and the left one is not in the bell.

Why would you have both a sousaphone and a tuba?
