Question

Musical instruments in which leather membrane is made to vibrate are known as _______________ instruments.
(A) Percussion
(B) Stringed
(C) Automatic
(D) Aberrated

Answer 1

Hint In our day-to-day life music becomes a part of ourselves. Music is a pleasant sound that soothes our minds when we listen to it. Music is generally produced by regular and periodic vibrations which are also continuous and uniform. It can be produced by various instruments. For example flute, guitar, etc.

Complete step by step solution:
Musical instruments can be made of various objects depending on their type. They are made of wood, metals, plastics, etc.
Music can be produced by various methods like blowing down a pipe, twanging an elastic band or strings, shaking or scraping, and also by banging. Hence, they are categories into three types such as percussion, wind, string. Instruments that consist of strings such as guitar are played, when strings are plucked its vibration that passes into the air can be heard as sound. Some instruments when blown the air inside them tend to vibrate and produce sounds for example flute and horn etc. Similarly in the case of percussion instruments it produces sound when we bang one of its surfaces. They are made hollow from inside and a surface of the membrane is attached to it which can be made of leather, plastics, etc. and when we bang them they produce sound by vibrations of the membrane. For example a table, bongos, etc.

Hence option (A) is the correct answer.

Note: We should not get confused about the music and noise both are types of sound. Music, as discussed, is the pleasant sound that is produced by continuous and uniform vibrations which are regular and periodic while noise is unwanted sound that results due to aperiodic and irregular vibrations that irritate our ear.
