This confirmed to me that music can be used.
A first idea that come to me was to making a soundtrack to the work i am making in studio practise. Convert it into a MIDI file and use free software to change it into notation.
From this stage i had two ideas;
- to print the music and keep photocopying it until it fades like the Wisps my work is about
- to upload it onto a popular music notation site and film someone trying to learn it
