For fans of America's show-style marching bands, halftime is game time. A squad of players, some 300 strong and armed with musical instruments, takes over the field, commanding attention with their stirring, spectacular display of choreography and musicianship. The football contest's controlled mayhem makes way for the blaring sound of trumpets and the heart-thumping rhythm of drums. Their sounds are rousing and rhythmic, exhilarating and entertaining, flamboyant and funky. As the bands pulsate and parade onto the gridiron, they are, for many, the real attraction of the game. As a team, they sport their own stars: a tuba player, a clarinetist, or a trumpeteer. Like a quarterback leading his team to victory, the drumline, a troupe of talented percussionists whose cadenced rhythm rocks the rafters of any dome, bring crowds to their feet with their daring feats of music and athleticism.
