What about legal aspects and intellectual property?

Ethic and intellectual property are important to us. It is of first importance that authors and publishers can keep proposing pieces to play. And for ourselves as well, it is important to respect our work.
ChorusPlay is not intended to, and will not, distribute music sheets.
What ChorusPlay brings is the capability for amateur musicians to prepare, then to use, layers and materials, these materials owning no musical elements by themselves.  In any case, and specifically when the partition is not from public domain, the end user will receive only the layers and materials and will associate them him/herselve with his/her own private copy of the partition. Each musician, and each group, is responsible to respect and contribute to the respect of legal aspects in respective countries. Using layers associated to scans of  private copies of partitions is fully in sync with national and international regulations.
