String instruments produce sound by the vibration of stretched strings. These instruments are played by plucking, bowing, or strumming the strings, causing them to vibrate and generate sound. Examples of string instruments include the violin, guitar, cello, double bass, and harp.
Wind Instruments:
Wind instruments produce sound by the vibration of air inside the instrument. These instruments are played by blowing air into a mouthpiece, causing the air column inside the instrument to vibrate and produce sound. Examples of wind instruments include the flute, clarinet, saxophone, trumpet, and trombone.
Percussion Instruments:
Percussion instruments produce sound by the impact of one object against another. These instruments are played by striking, shaking, or rubbing the instrument's surface. Examples of percussion instruments include the drum, cymbals, gong, xylophone, and marimba.
Brass Instruments:
Brass instruments are a type of wind instrument that produce sound by the vibration of the player's lips against a metal mouthpiece. The shape and size of the instrument's tubing affect the pitch and tone of the sound produced. Examples of brass instruments include the trumpet, trombone, tuba, and French horn.
