Introduction to Common Musical Instruments

Key Concepts

• String Instruments
• Woodwind Instruments
• Brass Instruments
• Percussion Instruments
• Keyboard Instruments

String Instruments

String instruments produce sound by vibrating strings. Common string instruments include the violin, viola, cello, and double bass. These instruments are played by drawing a bow across the strings or plucking them. The pitch of the sound is determined by the length, tension, and thickness of the strings.

Think of string instruments as the singers in an orchestra. Just as singers use their vocal cords to produce sound, string instruments use their strings to create music.

Woodwind Instruments

Woodwind instruments produce sound by blowing air into a mouthpiece and vibrating a reed or the air column inside the instrument. Common woodwind instruments include the flute, clarinet, oboe, and bassoon. The pitch is controlled by opening and closing holes along the length of the instrument.

Imagine woodwind instruments as the wind in a forest. Just as the wind makes the trees rustle, woodwind instruments create a gentle, flowing sound.

Brass Instruments

Brass instruments produce sound by vibrating the player's lips against a cup or funnel-shaped mouthpiece. Common brass instruments include the trumpet, French horn, trombone, and tuba. The pitch is controlled by the player's embouchure (how they shape their lips) and the length of tubing they buzz into.

Think of brass instruments as the powerful horns of a car. Just as car horns produce a loud, attention-grabbing sound, brass instruments create bold and vibrant tones.

Percussion Instruments

Percussion instruments produce sound by being struck, shaken, or scraped. Common percussion instruments include the drum set, xylophone, cymbals, and tambourine. The pitch can be fixed (like a drum) or variable (like a xylophone).

Imagine percussion instruments as the heartbeat of a song. Just as the heartbeat provides rhythm and structure, percussion instruments keep the tempo and add energy to the music.

Keyboard Instruments

Keyboard instruments produce sound by pressing keys that trigger a mechanism to sound notes. Common keyboard instruments include the piano, organ, and electronic keyboard. The pitch is determined by which key is pressed, and the volume can be controlled by the force with which the key is pressed.

Think of keyboard instruments as the piano in a house. Just as a piano provides a central place for musical expression, keyboard instruments are versatile and can play a wide range of melodies and harmonies.
