For four days around 350,000 spectators come to party and to listen to around fifty brass bands. In the restaurants or on the terraces there will sometimes be as many as twenty or thirty musicians playing at different tables. The trumpets vibrate like a swarm of bumblebees in madness and then at once their full power is unleashed. If an orchestra plays louder than its neighbours, the musicians will walk away with more money. The instruments are at their most brilliant when a group, having made it through to the final, practices in public on the last day.
