Dear Tatiana Kotcherguina,
Thanks for your upload of Moncayo's Viola Sonata. Unfortunately, it would appear that this work was first published only in 1991, which means that it is subject to a 50-year term from publication date in Canada since the works of Mexican composers are not subject to Canada's "Rule of the Shorter Term" thanks to the NAFTA Treaty. You will have to provide written permission from the estate of Moncayo or the appropriate copyright owner in order to upload any recording here. We will have to delete the recording you kindly uploaded due to possible copyright issues. Thanks, Carolus 23:19, 22 August 2010 (UTC) (IMSLP Copyright Admin)
