The biggest instrument in a brass band is the tuba.
["Instruments that made up a British Brass Band include:\n- Cornets\n- Tenor, baritone and flugel horns\n- Euphoniums\n- Tenor & bass trombones\n- Tubas - typically Eb and Bb"]
["Typically, trumpets and French Horns are not found in a British Brass Band, instead, British Brass Bands feature cornets."]
