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
A trumpet makes sound when the musician makes a buzzing sound while blowing air through closed lips and into the mouthpiece. The air causes a standing wave vibration in the air column inside of the trumpet, which travels down the instrument and is then manipulated by the pressing of the keys.Full Answer >
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 >
The modern concert harp produces a rich, ringing sound when the harpist plucks the strings or brushes her hand over them. As is heard in the beginning of the second movement of Caesar Franck's Symphony in D minor, the harp's sound is less dry than that of plucked pizzicato strings.Full Answer >
A violin produces sound through the vibration of its strings, which occurs when the player draws the bow over the strings and sets them in motion. From there, the bridge of the violin transmits those vibrations to the back and front plate of the instrument, causing the entire body of the violin to serve as a resonating chamber and amplifying the sound produced.Full Answer >
