Pulitzer Prize for Music: The Pulitzer Prize for Music is one of the seven American Pulitzer Prizes that are annually awarded for Letters, Drama, and Music.  It was first awarded in 1943.  Joseph Pulitzer did not call for such a prize in his will, but had arranged for a music scholarship to be awarded each year.  This was eventually converted into a full-fledged prize: "For a distinguished musical composition of significant dimension by an American that has had its first performance in the United States during the year."  Because of the requirement that the composition had its world premiere during the year of its award, the winning work had rarely been recorded and sometimes had received only one performance.  In 2004 the terms were modified to read: "For a distinguished musical composition by an American that has had its first performance or recording in the United States during the year."

Symphony No. 6 (Tchaikovsky): The Symphony No. 6 in B minor, Op. 74, Pathétique is Pyotr Ilyich Tchaikovsky's final completed symphony, written between February and the end of August 1893.  The composer entitled the work "The Passionate Symphony", employing a Russian word, Патетическая ("Pateticheskaya"), meaning "passionate" or "emotional", that was then mistranslated into French as "pathétique", "evoking pity", yet the mistranslation survived subsequent productions in every country but Russia.  The composer led the first performance in Saint Petersburg on 16/28 October of that year, nine days before his death.  The second performance, conducted by Eduard Nápravník, took place 21 days later, at a memorial concert on 6/18 November.  It included some minor corrections that Tchaikovsky had made after the premiere, and was thus the first performance of the work in the exact form in which it is known today.  The first performance in Moscow was on 4/16 December, conducted by Vasily Safonov.  It was the last of Tchaikovsky's compositions premiered in his lifetime; his last composition of all, the single-movement 3rd Piano Concerto, Op. 75, which was completed in October 1893, a short time before his death, received a posthumous premiere.
