Acoustic instruments generate sound physically and electronic instruments create sound electrically. There are four acoustic groups: percussion (
hit
or shaken), wind (woodwind and brass; blown), string (bowed or plucked), and keyboard (played with fingers).
What are musical sounds?
Musical sound,
any tone with characteristics such as controlled pitch and timbre
. The sounds are produced by instruments in which the periodic vibrations can be controlled by the performer.
How are musical sounds produced?
Sound is caused by
the simple but rapid mechanical vibrations of various elastic bodies
. These when moved or struck so as to vibrate, communicate the same kind of vibrations to the auditory nerve of the ear, and are then appreciated by the mind.
How do different instruments produce different sounds?
The reason the same musical note sounds different when played on various instruments is because
the harmonic overtones and envelope of each instrument is unique
. When a frequency is played, other frequencies, called harmonics, are created. Each instrument has a unique harmonic character.
What kind of sound is produced by musical instruments?
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.
What are the three types of musical instruments?

string instruments, wind instruments, and percussion instruments
.
What are the four properties of musical sound?
Since sound is a wave, it has all of the properties attributed to any wave, and these attributes are the four elements that define any and all sounds. They are the
frequency, amplitude, wave form and duration
, or in musical terms, pitch, dynamic, timbre (tone color), and duration.
What are the 3 types of sound?
- Infrasonic: It is a sound with a frequency of less than 20Hz. Elephants use Infrasonic sounds to interact with herds hundreds of km away.
- Sonic: It is a sound with the frequency between 20 to 20,000Hz. …
- Ultrasonic: It is a sound with a frequency more than 20,000Hz.
What is musical sound give example?
Musical sound is a pleasant, continuous and uniform sound produced by regular and periodic vibrations, e.g.,
sound produced by a violin, flute, tuning fork
etc. Noise is harsh, unpleasant sound produced by an irregular succession of disturbances and is discontinuous, e.g., sound produced by a gunshot, cracker bomb etc.
What are the main characteristics of musical sound?
Musicians point to three distinguishing characteristics of musical notes:
loudness, pitch, and timbre (or “quality”)
. There are other characteristics, but we will focus on these three in this module.
What is the source of all sounds?
The sound waves are generated by a sound source, such
as the vibrating diaphragm of a stereo speaker
. The sound source creates vibrations in the surrounding medium. As the source continues to vibrate the medium, the vibrations propagate away from the source at the speed of sound, thus forming the sound wave.
What is the most natural form of music?
| A–B Tone | D–E Tone | E–F Semitone | F–G Tone | G–A Tone |
|---|
What is the difference between sound and music?
Noise is sound with a continuous structure. Music is composed of sounds with a fundamental
frequency
and overtones. Noise is composed of sounds with frequencies that range continuously in value from as low as you can hear to as high as you can hear — not necessarily at equal intensity, however. … Music is ordered.
What instrument makes a loud sound?
