Universal Edition lists January, 25, 1905 as the world premier.Carolus wrote:So 1984 is actually the first publication then. Under the EU's rule of editio princeps, the 25-year term would have expired in 2010 had Zemlinsky died before 1940. However, he lived until 1942, which means it is protected there until 2013. It would be covered in Canada until 2035 unless there was a public performance before the composer withdrew the work. In the USA, it's locked up until 1/1/2049.
