If I wish to publish images of music staffs from NWC either in a book or on a website, or if I wish to upload videos of NWC playing music onto YouTube, do I need any special permission from NWC? If so, how do I obtain this?
No, you are free to publish any work that you create/own. We do not require, nor do we offer, any special permission.
That is very useful. Thank you very much for the clarification.
