Stringed instruments create sound through the vibrations caused by the musician's manipulation of the strings. This is achieved through strumming, striking, plucking or rubbing a bow across the strings. The strings are supported by a bridge that transfers their vibrations into the top of the instrument, referred to as the sound board. The sound board carries the vibrations to the instrument's body, which is called the soundbox or resonator.Know More
The soundbox of the instrument is relied upon to make its vibrations more audible. This is demonstrated with guitars, cellos and pianos through the use of their large, hollow body cavities. The opposite is true of stringed instruments that do not have a soundbox, such as electric guitars. In these cases, the instrument must be plugged in to an electric amplifier for its sound to be heard.
The tightness, weight and length of an instrument's strings affect the sound that it produces. For example, loose and heavy strings vibrate more slowly and create a deeper sound with lower notes. Thin, tight strings result in sounds with a higher pitch. Stringed instruments usually have a combination of thick and thin strings to create different notes. Musicians also control the notes of instruments like guitars and violins by grasping the strings at different points along the bridge. This changes the length of the strings and results in shifts in tone.Learn more about Musical Instruments
The harp produces sound when its strings are plucked, causing the strings to vibrate and move air through space. The strings are attached to a soundboard, which also vibrates and moves air, resulting in audible sound waves.Full Answer >
Flutes are reedless instruments that produce sound from the flow of air across a hole in a cylindrical tube. Reed instruments produce sound by focusing air into a mouthpiece that causes a reed to vibrate.Full Answer >
The sound waves in a guitar are produced by the vibration of the strings. The sound is transmitted via the pressure waves in the instrument.Full Answer >
Brass instruments rely on vibrations created by the movement of a musician's lips at the opening of the instrument. As the vibrations pass through the mouthpiece into the tube of the instrument, a unique sound is created, which can be manipulated into various volumes, notes and tones according to the movements of a musician's lips. The valves and sliding mechanisms on brass instruments are also used to manipulate sounds.Full Answer >
