An interesting concept and I've got many concerns in respect of the painful copyright situation that we already find ourselves in.
The fundamental point I suppose is should musical sequences (notes & rhythms), as mentioned in the clip, be owned by anyone or should they be freely available for use in society.
I recognise the desire to protect individual creativity but I also recognise the value of the resulting creativity being shared, used in the education & development process of other musicians (ie. covered) and then evolved or built-upon. I think we all know tunes that have a semblance or sequence of another tune embedded within it but is that a bad thing?
Copyright vs no copyright, cane vs synthetic.... it's another one for the debating chamber
