The four main types of stringed instruments used in an orchestra are violins, violas, cellos, and double basses.Fine bows for violins can use up to 150 horse hairs.Most civilizations have produced some kind of stringed instrument.Pianos are considered string instruments that are played by striking or hitting the string.The strings are usually made from nylon thread or steel wire.They don't change the length by pressing on a finger board, but there are a lot of different length strings helping them to make all sorts of sounds.įun Facts about How Stringed Instruments Work In this case the musician just plucks the strings with both hands. One is the harp where there can be a lot of strings of different lengths and weights. By pressing down on the string the musician changes the length of the string and, therefore, the note. With a guitar or a violin the musician vibrates the string with one hand and then presses down on the string, or strings, with the other hand.

How you make a note is different depending on the instrument as well. As we discussed on the main string instrument page, some are played with bows, some with picks, and some by plucking or strumming with your fingers. This is how different strings and different instruments are able to produce different notes.ĭifferent string instruments are played different ways.

Tightness - A tight string makes a higher note than a loose string.

Weight - Heavy, thick strings make lower notes than lighter thin strings.

Length - Longer strings vibrate slower and make lower sounding notes than shorter strings.

There are three ways that strings can produce different notes: The bridge then transfers the vibrations to the sound board which vibrates and uses the soundbox to amplify and make the sound loud enough for people to hear. Usually the strings rest on the bridge near one end.

When the strings vibrate their vibration is picked up by something called the bridge. Sound Moves from the Strings to the Soundbox The top of the soundbox, called the sound board, is usually made of a type of wood that vibrates. The soundbox is often the largest part of the instrument or the body of the instrument. This is called the soundbox or resonator. Most stringed instruments have something that amplifies the sound (makes it louder). It also wouldn't make a very interesting or musical sound. However, if you were to take a string and stretch it tight and pluck it, it likely would not make a very loud sound. Musicians make the strings vibrate by rubbing a bow against them, striking them, or plucking them. All stringed instruments make sound and notes by vibrating.
