How do string instruments make sound?
All stringed instruments make sound and notes by vibrating. Musicians make the strings vibrate by rubbing a bow against them, striking them, or plucking them. However, if you were to take a string and stretch it tight and pluck it, it likely would not make a very loud sound.
How do woodwind instruments make sound?
Woodwind instruments (clarinet, oboe) – Air is blown across the reed attached to the mouthpiece of the instrument, vibrating the air down the tube of the instrument to produce sounds. Different notes are produced by covering or opening holes in the instrument tube, changing the reed, and size of the instrument tube.
What is the small piece of wood in woodwind instruments called it is used to produce their vibrations?
The mouthpieces for some woodwinds, including the clarinet, oboe and bassoon, use a thin piece of wood called a reed, which vibrates when you blow across it.
How does an instrument make sound?
All musical instruments create sound by causing matter to vibrate. The vibrations start sound waves moving through the air. Most musical instruments use resonance to amplify the sound waves and make the sounds louder. Resonance occurs when an object vibrates in response to sound waves of a certain frequency.
What instrument makes a low sound?
bass drum
What makes a high sound?
We say high sounds are high pitch sounds, while low sounds are low pitch sounds. So, blowing a whistle produces a high pitch sound while hitting a drum produces a low pitch sound.
What causes different pitches in sound?
Sounds are determined by how an object vibrates. Sound waves travel at the same speed, but vibrate in different ways. Some vibrate quickly and have a high frequency or pitch, while others vibrate slowly and give a lower pitch.
How does frequency affect sound?
Sound moves through a medium such as air or water as waves. It is measured in terms of frequency and amplitude. Frequency, sometimes referred to as pitch, is the number of times per second that a sound pressure wave repeats itself. High frequencies produce more oscillations.
What is the period of 440 Hertz?
1 Hertz corresponds to 1 oscillation/second. Once we understand the meaning of a pitch or frequency of 440 Hz, we can ask a related question: how long does 1 oscillation of the vibrating string take? If the string oscillates 440 times in 1 second, then each oscillation will take (1/440) seconds.
