According to Soya Gulinskaya, who quotes a letter from Frederick Stock accepting the dedication, the symphony was dedicated - apparently after its premiere - to Frederick Stock,[3] a champion of Myaskovsky's music who later commissioned the 21st Symphony.
I accept with gratitude the dedication of your Thirteenth Symphony and shall repeat this and several of your major works on my programs in Chicago as well as on tour during the coming year.
Our mutual friend Prokofieff joins me in my highest estimation and admiration of your genius and I hope it will be possible for me before long to pay you a visit in Moscow so that I may have the pleasure of a personal acquaintance with you.
In the meantime, I am, with renewed expressions of highest esteem and most cordial greetings, very sincerely yours, Frederick A.
[3] The bleak and difficult music met a lukewarm reception, and the score was not printed until 1945.
