Question

In your own words,explain how the shape of a musical instruments can affect the sounds it produce ?​

Answer 1

Answer:

Although the pitch (how high or low a sound is) will be the same, a particular note sounds different on different instruments because they produce sound waves with different patterns (shapes and sizes). Bigger instruments tend to make lower and louder notes than small ones.Music is a special kind of sound that is pleasant to listen to. Musical instruments create sounds by making something vibrate. For example, guitars make sound when their strings vibrate. Most instruments are “tuned” to make a range of sounds of particular frequencies, which we call notes. These notes are made in a particular sequence to play a piece of music. Although the pitch (how high or low a sound is) will be the same, a particular note sounds different on different instruments because they produce sound waves with different patterns (shapes and sizes).

Answer 2

A crash course in sound

The answer to that question is at once highly complex and entirely simple. Instruments, one way or another, make sounds, and all sounds are vibrations which travel across particles that make up the air around us (for humans anyway). These vibrations are then transformed in our eardrum - itself a thin vibrating membrane, like you might find on a drum - to be translated, eventually, into something our brains ‘hear’. Phew, simple!

A musical instrument, in short, might itself vibrate, or have a part that vibrates, or amplifies and/or modifies another vibration. Those vibrations bump into neighbouring air molecules as per my description above, and you can think of those forming a wave like those in the figure below. A faster vibration creates more waves; the rate at which they move is called the ‘frequency’, which we measure in hertz (Hz), or cycles per second. The higher the frequency (or the more ‘bumps’ in the waveform) the higher the pitch.
