Question

Match the columns.

1. Wind instruments	a. Vibrating string
2. Stringed instruments	b. Frequency
3. Percussion instruments	c. Vibrating air column
4. Pitch	d. Vibrating stretched membrane
5. Loudness	e. amplitude

Accepted Answer

1.Wind instruments c. Vibrating air column

Wind instruments produce sound by vibrating an air column inside the hollow part of the instrument.

2. Stringed instruments a. Vibrating string

String instruments produce music by vibrating string of the instrument. Violin is an example of string instrument.

3. Percussion instruments d. Vibrating stretched membrane

Percussion instruments produce sound by vibrating a stretched membrane. The membrane vibrates on being struck. Tabla is an example of percussion instrument.

4. Pitch b. Frequency

The pitch of a sound depends on its frequency. Pitch is directly proportional to frequency.

5. Loudness e. Amplitude

Loudness depends upon amplitude of vibration. The loudness of the sound increases with an increase in the amplitude vibration. The unit of loudness is decibel.
