Well they are not all symphonic works, but Piano transcriptions of famous works for a solo instrument or voice, an ensemble of instruments and/or voices, or even a piece originally for solo or ensemble piano doesn't look like a more adorable title.
This playlist features piano transcriptions of Beethoven's nine symphonies (by Liszt), Dvorak's New World Symphony, late symphonies of Mozart and Schubert, Mahler's Symphony No.1 "Titan", Bruckner's 2nd, Berlioz's Symphonie Fantastique, Debussy's La Mer and his arrangement of Wagner, Tchaikovsky's Symphony No.4 and 6 "Pathétique", Stravinsky's Rite Of Spring, Prokofiev's Symphony No.1 "Classical", Smetana's symphonic poems My Country, Shostakovitch's Symphony No.10 (played by the composer) and his piano arrangement of Honegger's Symphonie Liturgique. And Glenn Gould's last recording, his piano transcription of Wagner.
As well as chamber works such as Mendelssohn's Octet, Franck's Violin Sonata (by Cortot), Richard Strauss' Serenade For 13 Wind Instruments (by the composer), Schumann's piano quartet (by Brahms) and quintet (by Clara Schumann). Amazingly, there are even piano arrengments (reductions?) of Fauré and Verdi's requiems, Mozart's Masonic Funeral Music, and Beethoven's Missa Solemnis.
Too many Liszt transcription of romantic lieders out there, so I only put in some hightlights, for Bach it's the same (virtually all Bach played on piano are transcriptions). In my other playlists you can find Brahms's own transcription for most of his symphonic and chamber works, and piano four-hand version of Mozart and Beethoven operas. I left them out of this one to avoid duplication.
I don't think there would be an organ transcription playlist so I also included organ transcription of the Mahler 5th and Bruckner 8th.
Here's the Spotify playlist: Piano Transcriptions (335 tracks, total time: 1 day) It may work better in Album view (easier to tell one piece from another) If you find other interesting transcriptions please leave a comment or send to my Spotify inbox. Thanks.
If you find this one too overwhelming, go to the end of the playlist and listen to James Rhodes play the solo piano version of the Romance from Chopin's Concerto No.1.
