The International Confederation of Societies of Authors and Composers (CISAC) is a non-profit non-governmental organisation which represents, in over a hundred countries, collecting societies managing copyright relating to, inter alia, musical works.
The collecting societies acquire the management of those rights either by direct transfer from the authors or by transmission from another collecting society managing the same categories of rights in another country. They grant exploitation licences to commercial users, such as broadcasting undertakings or organisers of live shows. The prices of those licences are the source of the royalties that the authors receive, after the management expenses of those collecting societies have been deducted. Here to read more.
