> Anton Bruckner, Symphony No. ° 3, transcription for piano 4 hands (perhaps in collaboration with Rudolf Krzyanowski), 1878 or 1880.
The "Symphonisches Praeludium" is something of a mystery. If not by Mahler himself, it certainly hails from the Vienna of his student days. It was unearthed in the late 1970's in the Austrian National Library: a piano transcription, by one Heinrich Tschuppik, made from what the title-page described as a score "from the year 1876, supposedly by Anton Bruckner" that had been copied "by the Bruckner-pupil Rudolf Krzyzanowski". The sound and style of the Prelude certainly has much of Bruckner about it, and not a little of Wagner. Structural peculiarities nevertheless led some musicologists to hear in it the work of a younger composer inspired by Bruckner, rather than Bruckner himself. Since Rudolf Krzyzanowski was a close and admiring student friend of Mahler's, the tantalizing possibility arose that it might just be one of Mahler's own lost student compositions. The mystery may never be solved. As thematic connections are known to exist between Mahler's later works and the symphony by Hans Rott, another of his student companions, it would be reasonable to assume that there was a fairly close community of styles and even musical ideas within Mahler's circle of the later 1870's, whose members influenced and inspired each other. Mahler must surely have known and identified with this expansively brooding symphonic movement, even for if he did not actually compose it himself. If it is an unknown work by Bruckner, then its survival in a copy by one of Mahler's friends makes it all the more valuable as an indicator of the kind of music in which they steeped themselves and out of which the individual style of their most famous colleague would develop.

It is contained in a LP privately recorded in Japan, in 1960, by a mysterious "Mr Y" that say of have buy this recording in a sound test of G&T, with a white label, with the autograph that Mahler writes with his own hand, and with the words "Gustav Mahler plays Mendelssohn's Rondo". On the liner notes gave the year 1905, when Mahler was briefly visiting London. But the original record was never shown to the public, and nobody knows where the record is right now.
