I had the first bit of my piece, from the Radio Times, worked out. Now I needed to transfer it onto staves in Garageband. Yes, that is what I use, being non-musical, it opens up a new world to me of creating experimental, electronic music.
This first picture shows all the points from two days, placed on a stave, ready to be inserted into GarageBand.
Here are some early idea's with the stave's temporarily removed. These were intended to be used as transparencies but I decided to do something different, move away from print and back into the moving image.
