Brass instruments are musical instruments that produce sound through vibrating brass. Common brass instruments featured include trumpets, trombones, French horns, tubas, cornets, and bugles. Woodwind instruments produce sound when the player blows into a mouthpiece, causing a reed or air column inside the instrument to vibrate. Examples shown are clarinets, oboes, bassoons, saxophones, and flutes. String instruments include instruments that are played by drawing a bow across strings or plucking the strings. Violins, cellos, guitars, harps, and double basses are pictured. Percussion instruments make sound when struck and include drums, maracas, triangles, and cymb
