Qualities of sound. The sound

4.  Sound is a type of energy made by
vibrations. When any object vibrates, it
causes a movement in the air particles
producing SOUND WAVES.
 When our ear is close to the vibrations of
the sound waves, we hear the sound.

5.  Sound can travell very fast. Sound
travells at 340 meters per second.

6.  Reverberation or reverb: When the sound
waves find an obstacle, they back off.
That explains the fact that music does
not sound the same way in different
places.

8.  Sound, is collected by the pinna and
directed through the outer ear canal.
 The sound, makes the eardrum vibrate,
which in turn causes a series of three tiny
bones( the hammer, the anvil and the
stirrup) in the middle ear to vibrate.

10.  The threshold of
hearing is the minimum
sound level that an
average ear can hear,
10 decibels.
 The sound which
produce pain is the
threshold of pain, 120
decibels.

11.  Humans can normally hear sound
frequencies between 20 and 20,000
Hertz, that is between 20 and 20, 000
Vibrations per second.
 When a sound waves frequency lies
above 20,000 Hertz it is called an
ultrasonic wave, and when a sound
waves frequency lies below 20,000 Hertz
is called an infrasonic wave.

12.  Silence, is the relative or total lack of
audible sound. In music, silence is as
important as sound.
 Some composers have used silence like
main element of their creations, such as
John Cage with his musical composition
4`33”.

13.  Noise pollution, is a displeasing human,
animal or machine-created sound that
disrupts the activity or balance of human
or animal life.
 Noise pollution, can cause hypertension,
high stress levels, sleep disturbances, etc.

15.  The sound is an essential element in a
music creation.
 The study of its qualities and elements
and the way in which they are organized
is so called musical language.

16.  INTENSITY
 DURATION
 FREQUENCY
 TIMBRE/ TONE COLOR

17.  How loud of soft the sounds are. The
intensity of a sound is measured in
decibels (DB).
 The intensity of a sound depends on the
amplitude of the sound wave.
 Amplitude is the size of the vibration, and
this determines how loud the sound is.

18.  How long or short notes are.
 The duration of a sound depends on the
persistence of the sound wave, that is,
the amount of time in which the
vibration is extinguished.

19.  The highest persistence, the longest
sound.
 The lowest persistence, the shortest
sound.

20.  Figuras: signos que representan la
duración del sonido

21.  A rest: Is an interval of silence in a piece
of music. Each note has got a rest.

22.  Compás: división del tiempo en partes
iguales.
Numerador:
número de tiempos
Denominador: figura unidad de tiempo

23.  Music is often divided up into units
measures or bars.
 Simple time measure, consist of two
numerals, one stacked above the other:
A.The top number tells us how many beats.
B.The bottom number tells us what kind of
note gets the beat.

24.  The most common simple time signatures
are 2/4, 3/4, and 4/4.

25.  Tempo: velocidad de interpretación de
una obra musical
 Largo: muy despacio
 Adagio: despacio
 Andante: normal
 Allegro: deprisa
 Presto: muy deprisa

26.  Frequency, the perception of a high or
low sound, is mesure in Hertz ( Hz).
 Frequency is the speed of the vibration.
 The highest the frequency, the highest
sound.
 The lowest the frequency, the lowest
sound.

27.  The timbre, is the combination of
qualities of a sound that distinguishes it
from other sounds of the same pitch and
volume.
 It depends on the mixture of the
fundamental sound and its harmonic
sounds.

music.
