Cello Sonata No.1, Op.12 (Myaskovsky, Nikolay)
It is unlikely that this work is public domain in the EU, or in any country where the copyright term is life-plus-70 years. However, it is in the public domain in Canada (where IMSLP is hosted) and other countries where the term is life-plus-50 years (like China, Japan, Korea and many others worldwide). As this work was first published before 1923 or failed to meet notice or renewal requirements to secure statutory copyright, it is very likely to be public domain in the USA as well.
Scores and Parts
Moscow: P. Jurgenson, n.d.. Plate 36931.
Moscow: Muzgiz, 1926, (1945). Plate Г.M.И.M. 1266. (revised)
Strangely the plate numbers of both Jurgenson and Muzgiz were imprinted simultaneously. However obviously this is the revised version as there are differences in the cello part.
|Work Title||Cello Sonata No.1|
|Movements/Sections||2 movements (sometimes divided as 3)
|Year/Date of Composition||1911|
|Copyright Information||This work is found on the NIE list (V8001P620). The NIE can only refer to a revised version issued after 1922. The Jurgenson edition here is absolutely public domain in the USA, as there was nothing issued after 1918 with the Jurgenson imprint. Of course, there's always the possibility that the US claimant of the NIE (Schimer/Music Sales) was simply lying, in which case they should be prosecuted for perjury.|
|Piece Style||Early 20th century|
Second version was, indeed, composed (or published? Composed, I think) in 1930- see the External Link (or many other sources!) - though according to Worldcat it was also published in 1926 (either a version 1.5 or a reprint of the 1911 (1913-published) version?). (.)) I don't know when the 1930 version was published- possibly not before the 1950s (in the Miaskovskii collected works edition)?
