This example follows on from the 3Z (Zoom In Zip Up Zoom Out) previous section, which explains the approach in detail.
We have chosen the example of an orchestra because so many people with CVI enjoy music. The techniques and understanding will range considerably between those for a profoundly disabled person with CVI (CVI Classification 1) and a high functioning person with CVI (CVI Classification 3), but the principles are the same.
We have chosen the piece of music Carnival of the Animals by Saint-Saëns to help build up knowledge of the orchestra, and will be learning about:
Start with the orchestra - too much visual information, so we zoom in
To the double basses
Let's zoom in some more - what does a double bass look like?
Look how big they are?
If this is still too complex, zoom in some more and simplify
For a child like Daniel, we may have to zoom in further
So what does it sound like?
It's fast. Here's a slow piece
Now, let's hear our double bass in Carnival of the Animals, it is the elephants
Elephants are big and walk slowly (from here you could look at elephants in more detail, including where they live, the shape of the elephant, films of elephants moving, something leathery for the texture of the skin and sounds of their call).
Listening to the piece of music, did you hear the double bass? The name for an object that creates a sound that is music is called a musical instrument.
The orchestra has many different musical instruments
There was another instrument playing with it, a piano
Here's a piano
That's a lot of visual information, let's zoom in
This is what a piano sounds like:
Let's zoom back out again, and listen to our piano and double bass together as the elephants in carnival of the Animals
So, we are starting to be able to create a more complex picture and understanding. We have zoomed in to look at the parts, and as knowledge develops, we can start to zip those parts together (zooming out). There are many ways to add to the build-up of experience, including of course an opportunity to feel and play the instruments.
The Kangaroos in the Carnival of the Animals are from two pianos playing together:
Kangaroos are animals that jump, the music is meant to sound like them bouncing around.
Staying with the music, and the pianos, here's another animal, this time a swan
Listen to the music, can you hear the piano?
There's another instrument, it's called a cello. Let's go back to our original orchestra and see if we can find the cello.
A cello looks a lot like a double bass, but is smaller and sounds a little higher
Listen to a cello, and a double bass playing together
So now let's look at the section of the orchestra with double basses and cellos
Combining an increasing knowledge and understanding of the parts, we are able to zip them together, to develop a meaningful understanding of the bigger whole. We still have a little work to do to learn an understanding of the whole orchestra, but step by step, as a new 'part' is learnt., it can be zipped to the increasingly bigger whole, using visualisation from increasingly strong and complex memories formed by our experiences (see Recognition).
This Applies to Everything
We have used what might be considered a very academic example, something that should be taught in school maybe. This was just to illustrate the approach, but having limited simultanagnostic visual attention affects everything.
