Intensit y tells us if a sound is loud or quiet . In music, we call this dynamics and we express them with dynamic indicators . They are Italian words and we usually wr ite their abbrev iations under the stave. To show that the dynamics of the music gradually increases or decreases , we use some symbols called hairpins. 16.

FIND OUT what a speech pathologist is. The voice is an exceptional instrument that we must learn to look af ter. Bad habits like shouting, clearing your throat or coughing, drinking cold drinks, not resting enough, spending too much time in smoky places or singing in the wrong tessitura can damage our speech organs. Voice disorders are called dysphonia. Dysphonia that isn't cured or treated properly can become aphonia, which is total voice loss. Another example of chronic damage is vocal nodules, which are growths that form on the vocal cords and produce hoarseness and diff iculty in making certain sounds.

R E A D I N G If music is made up of sounds, how can people with hearing loss enjoy it? We often think that music is exclusively for people who can hear, but the experiences of people with hearing loss make us rethink how we understand sound. Hearing is a sensation that happens in the brain when sound waves made by a vibrating object reach it. To be precise, the perception of sound happens in a place the size of a golf ball, called the auditory cortex. According to the latest research, people with hearing loss register sounds in the same part of the brain. However, instead of analysing information that they receive from the hearing organs (which are damaged), they process the vibrations of the sound that they perceive with their whole bodies. Anyone who has been near a loudspeaker in a disco knows how it feels when music makes your whole body vibrate. This discovery can help us to understand why so many people with hearing loss have dedicated their whole lives to music, overcoming their physical limitations and perceiving sound in different ways. Beethoven is one of the most well-known examples. It's said that he cut the legs off his piano to perceive the vibrations more clearly when he played. And his hearing loss didn't stop him from composing some of the most famous pieces in the history of music. Today, Evelyn Glennie is one of the most well-known musicians with hearing loss. She has won two Grammy Awards and recorded many albums. This exceptional percussionist can identify the exact pitch of any note by feeling its vibration in different parts of her body: ‘For some reason, we tend to differentiate between hearing a sound and feeling a vibration,’ she says, ‘but they're actually the same thing.’ Fortunately, there are more and more musical activities designed for people with hearing loss. In some concerts, for example, balls filled with air are given out so that the audience can feel the music in their hands. And sometimes wooden boxes are installed for people to lie on and feel the vibrations all over their bodies. After all, nobody wants to live without the pleasure of music. Can people with hearing loss listen to music? Key questions 1 What do we call the part of the brain that perceives sound?

CONNECT WITH REALITY How many different sounds can you make with your body? When we clap our hands or tap our feet, can we call it music? Which everyday sounds bother you? Can excessive sound or noise be bad for our health? When is it better to be silent? 1 Rhythm in our blood
Rhythm is present in many aspects of nature: we can f ind it in our heartbeat , the waves in the sea, the cycle of day and night or the seasons of the year. When we listen to music or perform a rhythm or a melody, we naturally clap or tap our feet to the beat . 1. Rhythm and beat 1. ACCOMPANY Where Is t he Love? by Black Eyed Peas with this series of sounds. In music, rhythm means a pattern of sounds. These patterns are organised into beats. The beat means the equal parts in which musical time is divided. Some beats are louder than others. This creates a different emphasis when the louder beat is one in every two, in every three or in every four. 2. BEAT OUT these rhythms by patting your legs. Emphasise the louder beats. ➔ Ever y two beats (The Syncopated Clock by Leroy Anderson): 1 2 1 2 1 2 1 2 ➔ Ever y three beats (Walt z of t he Flowers by Pyotr Ilyich Tchaikovsky): 1 2 3 1 2 3 1 2 3 ➔ Ever y four beats (Baby Elephant Walk by Henr y Mancini): 1 2 3 4 1 2 3 4 2. Body percussion The human body is the perfect instrument. We can sing beautiful melodies with our voices and make all types of rhythms with body percussion, like clapping our hands, clicking our fingers or patting our legs. clap f inger click pat your hand on your chest f inger click 1 2 3 4 8 I Rhythm in our blood

The haka 5. FIND on the Internet the All Blacks rugby team performing the haka. What do their movements look like? The haka is an ancient war dance from the Maor i culture in New Zealand . It consists of a ser ies of v igorous movements per formed simultaneously in a group, accompanied with body percussion. At the same time, the per formers recite a chant with loud voices . 3. Writing music 6. LISTEN to the Allegro f rom Cello Concerto in B Minor by Antonin Dvorák. Could you easily learn this piece by heart? An effective way to remember music is to wr ite it down. Western musical notation is a code used all over the world for representing music graphically. It consists of var ious elements . The stave We write music on a stave, a set of five lines and four spaces where we write the notes and all the other musical symbols. We count the lines and spaces of the stave from the bottom up. One-line stave When we aren' t per forming musical notes , but only rhy thms , we use a stave with just one line. The clef The first thing that we wr ite on the stave is the clef, which shows the name of each note on the stave. There are several t y pes of clef, but the most common is the treble clef. It star ts on the second line of the stave and it shows the note Sol or G on this line. 7. LEARN how to write the treble clef and practise it in your notebook. & œ Other clefs ➔ We use the bass clef to write low notes. It starts on the fourth line of the stave and it shows the note Fa or F on this line. ? œ ➔ We use the neutral clef to write rhythms, which is why it doesn't show pitched notes. / 5 4 3 2 1 4 spaces 5 lines 4 3 2 1 For a long time, music passed f rom one generation to the next orally, but today we have musical notation to represent it graphically so that it endures over time. 10 I Rhythm in our blood
4. Properties of sound There are four proper ties that help us to distinguish one sound from another : duration , pitch , intensit y and timbre. We can show all these proper ties with musical notation. Duration 8. SAY the correct order of the rhythms. A 44 / œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ B 44 / œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ C 44 / œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ œ Duration tells us if a sound is long or shor t . We represent it with note values and their cor responding rests . The note value that usually represents the beat is the crotchet , but it could be any note value. name note value rest equivalent semibreve 4 crotchets w h q e x minim crotchet 1 crotchet 2 crotchets quaver 1/2 a crotchet semiquaver 1/4 of a crotchet 9.

Then make up a third rhythm and write it on a one-line stave. 44 / ˙ œ Œ œ œ œ Œ œ œ œ œ œ œ œ 44 / œ Œ ‰ œ j ‰ œ j œ œ œ œ œ œ œ œ œ œ œ ˙ 1 2 Parts of a note ➔ The parts of a note value are: ➔ When quavers and semiquavers go together, their f lags join each other like this. iq jjjq flag stem notehead e q 11

In the air, sound waves travel at a speed of 340 metres per second, but they travel at almost 1,500 metres per second in water. This is why dolphins and whales can communicate with each other at distances of up to 30 kilometres. Sound When an object v ibrates , it emits sound waves that travel through the air, water or another medium until they reach our ears . The sound wave of a long sound v ibrates for longer than the sound wave of a shor t sound . long sound short sound The sound wave of a high sound v ibrates more quick ly than the sound wave of a low sound . high sound low sound The sound wave of a loud sound has taller waves than the sound wave of a quiet sound . loud sound quiet sound 20. LOOK at the change in this sound wave and choose the right answer. From a scientific point of v iew, sound waves are responsible for the difference of sound and noise. The sound waves of music are regular and organised , and they feel pleasant , while the sound waves of noise are ir regular and disorganised , and they feel unpleasant . sound noise At f irst it's high and then it gets lower. No! It starts forte and ends piano. 1 2 16 I Rhythm in our blood

When we hit it , it vibrates 440 times per second (440 Hz). This is the f requency of the note La or A. How sound is measured A lthough we can' t see sound waves travelling through air, they are a physical phenomenon that can be measured and analysed with special dev ices . The duration of a sound depends on how much time a sound wave lasts ( longer or shor ter waves) and we measure it in seconds. The pitch of a sound depends on the frequency of the v ibration of the sound waves (number of v ibrations per second ). We measure it in her tz (Hz). The intensit y of a sound depends on the amplitude of its waves ( larger or smaller waves). We measure this in decibels (dB). 21. FIND OUT how many decibels these sounds approximately have. ➔ The threshold of hearing is the minimum sound level that we need to hear a sound. Humans can hear sounds louder than 0 dB. ➔ The threshold of pain is the sound level f rom which a sound becomes unbearable and painful . For human beings this threshold is 120 dB. 17
The hearing organs 22. FIND OUT what functions earwax has in the human body. We can hear sound and noise thanks to our ears, which have three par ts: Outer ear: in this par t , the ears receive sound waves and send them through the ear canal . Middle ear: in this par t, a membrane called the eardr um vibrates when the sound waves reach it and it transmits these vibrations to a ser ies of small bones.

Then share it with the rest of the class and discuss. A soundscape is the result of all the sounds in a space at a given moment . The sound of a place is unique, like its traditions or the accent of its inhabitants . Today, our soundscapes have become more uniform. The sound of traffic is generally present in most people's lives , threatening the diversit y of our acoustic env ironment . outer ear middle ear inner ear ear auditory nerve cochlea eardrum ear canal 1 18 I Rhythm in our blood
24. RECORD a soundscape and play it for the rest of the class. Then answer. ➔ Can you hear sounds of human activity? And sounds f rom nature? ➔ Do some sounds stand out more than others? 25. MAKE a summer storm soundscape with body percussion. Follow the instructions. 7 THE STORM IS GOING AWAY. Pat your legs again and gradually less quickly and less hard. 8 THE LAST DROPS OF RAIN. Click your f ingers gradually more slowly, until you stop completely. 5 THE RAIN POURS DOWN. Pat your legs vigorously and quickly. 6 THERE IS MORE THUNDER . Hit the table hard, and then do it twice more gently. 3 THE RAIN GETS HEAVIER. Pat your legs with alternate palms and gradually increase the speed and intensity. 4 THE THUNDER STARTS. Hit the table hard, and then do it twice more gently. 1 A LIGHT BREEZE STARTS TO BLOW. Rub the palms of your hands together gently. 2 SOME RAINDROPS START TO FALL . Start to click your f ingers, f irst slowly and then gradually more quickly. 19
Noise pollution 26. ASSESS the sound level at your school . ➔ In a group, measure the sound level in your cl assroom during a lesson , writing down the ma ximum and minimum levels . You can use a sound meter or download an app to measure the sound level with your mobile phone. ➔ Write a list of possible measures to reduce noise at your school . In groups of four, discuss your proposals and make a new list that includes the measures that you f ind more effective. ➔ Make some posters of your measurements and hang them in the halls and classrooms to raise the awareness among other students at your school . Excessive sound and noise around us is called noise pollution , and it can be ver y annoy ing and even bad for our health. According to the WHO ( World Health Organisation), a level of more than 65 dB around us is dangerous for our physical and mental health . However, more than 130 million people are exposed to this level of noise ever y day. Levels of sound and noise up to 80 dB can cause listener fatigue, stress , insomnia , ir r itabilit y and aggressiveness . The r isk increases above 90 dB. This level can cause ir reparable damage, such as par tial or complete loss of hear ing. An isolated noise of over 160 dB ( like an explosion or a gunshot) can cause a per forated eardr um or other ir reversible injur ies . Our behav iour is key to reducing noise pollution , as we all are par tly responsible for the levels of sound and noise in our sur roundings . Silence 27. LISTEN to the Allegro f rom Symphony No. 2 by Anton Bruckner. Can you imagine how this piece of music would sound without rests? What is the importance of silence in our everyday life? 28. COMPLETE this melody with only rests in your notebook. Then perform it . 44 & œJ œ œ œ œ œ œ œ œ j œ œ œ œ œ Silence helps us to memor ise, learn and , in general , it has ver y positive effects on us and our sur roundings . Without silence, music can' t exist , as music is the result of the combination of sound and silence. The recommended limit in classrooms is 35 dB, but in reality the levels of noise in primar y and secondar y schools of ten reach 80 dB. A long time ago, a philosopher called Pythagoras said: ‘A fool is known by his speech, a wise man by his silence.’ 20 I Rhythm in our blood
7. Enjoy the concert! William Tell by Gioachino Rossini Gioachino Rossini was born in Italy in 1792 . Both his mother and father were musicians . By the time Rossini finished his musical studies , he already stood out as a composer. He wrote all kinds of operas . In 1823 he moved to France, where he premiered his opera William Tell in French six years later. A lthough Rossini composed it at the age of 32 , lived for 40 more years and was a celebrated and famous composer in his time, he never composed another opera . William Tell is based on the stor y of a crossbowman famous for his good aim. The governor of A ltdor f (Switzerland ) got angr y when he heard that William didn' t bow when he passed by a symbol of the governor's power one morning. The governor ar rested him, but he promised to release him if he passed a test . William Tell had to shoot an apple off the head of his own son , with just one ar row, from 80 steps away. He split the apple r ight down the middle. When they asked him why he wanted two ar rows if he could only use one, Tell replied that the other ar row was to kill the governor if the first ar row missed . They impr isoned the crossbowman again , but he managed to escape and kill the governor. The Swiss people revolted and the fight for independence star ted . 29. LISTEN to the end of the Wi lliam Tell Overture.

R E A D I N G If music is made up of sounds, how can people with hearing loss enjoy it? We often think that music is exclusively for people who can hear, but the experiences of people with hearing loss make us rethink how we understand sound. Hearing is a sensation that happens in the brain when sound waves made by a vibrating object reach it. To be precise, the perception of sound happens in a place the size of a golf ball, called the auditory cortex. According to the latest research, people with hearing loss register sounds in the same part of the brain. However, instead of analysing information that they receive from the hearing organs (which are damaged), they process the vibrations of the sound that they perceive with their whole bodies. Anyone who has been near a loudspeaker in a disco knows how it feels when music makes your whole body vibrate. This discovery can help us to understand why so many people with hearing loss have dedicated their whole lives to music, overcoming their physical limitations and perceiving sound in different ways. Beethoven is one of the most well-known examples. It's said that he cut the legs off his piano to perceive the vibrations more clearly when he played. And his hearing loss didn't stop him from composing some of the most famous pieces in the history of music. Today, Evelyn Glennie is one of the most well-known musicians with hearing loss. She has won two Grammy Awards and recorded many albums. This exceptional percussionist can identify the exact pitch of any note by feeling its vibration in different parts of her body: ‘For some reason, we tend to differentiate between hearing a sound and feeling a vibration,’ she says, ‘but they're actually the same thing.’ Fortunately, there are more and more musical activities designed for people with hearing loss. In some concerts, for example, balls filled with air are given out so that the audience can feel the music in their hands. And sometimes wooden boxes are installed for people to lie on and feel the vibrations all over their bodies. After all, nobody wants to live without the pleasure of music. Can people with hearing loss listen to music? Key questions 1 What do we call the part of the brain that perceives sound? What function does it carry out? 2 Which two musicians with hearing loss are mentioned in the text? 3 Watch a video of Evelyn Glennie on the Internet .
