Part Three: Structuring the sound

Structuring a piece of music doesn't have to require any complex computer equipment or software, such as the multitrack DAW above. For many of the soundscape activities that your class could engage an audience, students will be making the layered sound themselves as a live performance piece. But recording the music digitally or performing a soundscape live still requires the students to have an awareness of how they can impact the mood of the sound they are making, the impact that this music will have on a potential audience. It requires an awareness of elements of music, beat, rhythm, pitch, tempo, dynamics and tone colour. It requires students to "structure the sound".


For example, for the choir to create their sound art piece of a thunderstorm they needed an awareness of how the tempo of their fingers clicking out of order created an impression of light raindrops falling, how the deeper pitch of peoples legs pounding on the ground sounded very similar to thunder and how this compared to the earlier sounds of fingers clicking - bringing in ideas of dynamics- the volume of the piece changed as more members of the choir clicked their fingers and then got suddenly louder with the thunder. The piece followed a narrative structure, it didn't start in the middle of the storm, the rain picked up and it raised to a crescendo of thunder and rain. A piece of sound art requires some awareness of music theory.

Within the topic of soundscapes, you may have the opportunity to introduce some basic music elements. When discussing the elements of music try and get students to think about the impact that these elements have on the audience response. Encourage students to think about how a change in each element changes the mood of the soundscape. E.g. “If the tempo increases how might that make the audience feel?” or “If the soundscape is really soft, and then gets suddenly loud how might the audience feel?”.

Here are some definitions and supporting ways of teaching such concepts in your classroom.

Rhythm 

Is there a certain rhythm to any of the sounds? What rhythm would footsteps make if you were walking through the bush?

Rhythm is made up of beats and rest. Rhythm can be thought of as patterns in the sounds . . . think of the rhythms that are in nursery rhymes or clapping rhythms.
A good game to play with children when introducing the concept of rhythm is a simple game called the clapping game. It encourages good group work and listening skills and can help to develop the children’s sense of rhythm.
There are 2 teams, 1 team consists of the teacher and the other is the whole class. The teacher claps a pattern and the children then copy the pattern. If the teacher only claps once then the children must not clap. If they do then the teacher gets the point and if they do not then they get the point.

Tempo 
 What is the tempo of the piece? Is there more than one tempo in the soundscape? Can the tempo change?

Tempo is the speed or the pace. An easy way to describe the tempo a piece could be comparing it to the speed we walk/run. Walking, jogging, sprinting etc. Tempo can affect the mood of the piece. A fast tempo can sound exciting or frantic. A slow tempo can sound peaceful or sad. In a sound scape of New Zealand bush the tempo may be determined by the footsteps we hear. The person may be walking so soundscape may sound quite relaxed, or the person could be running which again would give the piece a completely different feeling. Think of how tempo of someone’s breathing changes the mood. To understand tempo students to attempt to create a small clapping piece where claps stay in time with a rhythm, the rhythm can increase in tempo until the students are clapping so fast that it is extremely hard to keep in time with the beat.

This is an interactive lesson that introduces the concept of tempo for younger children

Pitch 
 What low sounds can we hear in this piece? High sounds?

High sounds, low sounds and everything in between.
To introduce pitch to children there is a game called high, low and middle.
Just play a note on a pitched instrument (you don’t have to play the instrument to do this - just play random notes one at a time), this could be a piano, ukulele, guitar, glockenspiel etc.
Then play either a high note (they stretch up), a low note (they curl up like balls) and middle note (make a cross with arms). You can always turn the game into a challenge and eliminate any children that get it wrong or are slow or the last to act.

Melody 
What are the tunes that you can hear in the piece? What things in this sound scape are creating the melody? Are there repeating melodies?

Melody is the tune in a piece … a catchy tune that has notes that change in pitch. For the purposes of soundscapes it depends which sort of approach you want to take, some melodies such as bird calls could be used as a repeating motif in the piece.

Dynamics 
 Is this piece loud or soft?

Dynamics are related to the volume of the piece
Dynamics can change suddenly, soft straight to loud, or the dynamics can get gradually louder (crescendo) or gradually softer (decrescendo). 

In a soundscape the there may be different dynamics for different sounds at the same time. The sound of the river may start to fade out as the rustling of the trees gradually comes in; this would indicate that you are walking away from the river towards some trees.

This is another great interactive lesson that introduces the concept of dynamics for younger children

Texture   
How many layers does this piece have? How many things are going on at the same time?

Texture of a piece is essentially the amount of layers a piece has and how those layers are related. Clicking on the bold links will link to some midi examples.

To get technical …
Monophonic – only one thing going on, one melodic line

Homophonic – there is one melodic line but there is an accompaniment (normally chords) going on underneath it to support it (you could compare this to a backing track, you can tell something is missing)


Polyphonic – two or more melodic lines going on at the same time, each melodic line could stand alone and still sound complete. Good examples of polyphonic texture are rounds/cannons.

Throughout one piece, it may have different textures.

In a soundscape you may want to start off with just one thing happening (monophonic) and gradually layer things onto as Andrew and Jonathan have done in their soundscape. If the soundscape is based on taking a walk in the bush, the layering of the sounds will depend on what you are ‘walking past’ at the time.

Timbre/Tone Colour
Does this piece sound light or dark?

Timbre is how the instruments sound, the tone colour. It can be described in many different ways, bright or dark, thick or thin, harsh or soft etc. The timbre of a instrument/element will have a direct effect on the mood of the piece. Think of the sound of wind. We could use bullroarer to create the sound of wind, the timbre of that could be described as dark. Or a group could make soft whooshing sounds, the timbre of this could be described as gentle.

This website will be an interesting example to explore on structuring sound in a modern recording, in this example a music video from the Grammy Award winners Arcade Fire can be "remixed" and the different elements of the song can be removed. Students can identify what different elements or layers of the song achieve and that music can be comprised of layers.

As students work structuring their sounds they can create with their voices, found and constructed instruments and body percussion, they need to keep in mind what story the sounds are telling, how will this contribute to the audience's understanding. Utilising some effective feedback and feedforward  with students can help in this process, scaffolding students understanding and getting students to develop their own ideas of how to improve their piece of music. A good idea is to record the students work on Garageband so that they can hear themselves and then address any issues with the sound, perhaps the rustling paper they are using for leaves is rustling too loud.
