How do you produce sound out of string instruments?
Pluck the string with your finger or with anything (like a pick or the hammer of a piano) and it will cause the string to vibrate at a frequency which is determined by the thickness of the string and the length of the string (which is a fixed length on a piano, but is determined by where you fret (push down on with your fingertip) the string on instruments like guitars and violins. The frequency of the vibration determines the note... since sound IS vibration.
How does decreasing the length of a guitar string change its vibration?
Well, the vibrations from the strings would have more room to vibrate in the body, thus producing a deeper sound.
What factors decides frequency of vibration of a plucked string?
The four properties of the string that affect its frequency are length, diameter, tension and density. These properties are- When the length of a string is changed, it will vibrate with a different frequency. Shorter strings have higher frequency and therefore higher pitch.
How does a violin produse music?
A violin produces sound by the vibration of the bow on the string, or the vibration when you pluck a string.
How do string instruments make sound?
Different string instruments have different ways to make sound. Pianos hit the strings with a felt covered "Hammer", a Guitar creates a sound when the guitar player plucks a string. Either way, each string instrument makes sound by the vibration of the string.
