Liszt used Beethoven's original tempo markings for his Beethoven symphony transcriptions, and they are usually too fast to play on piano.
The etude was not actually meant to be played at Chopin's original half=69 marking - I quote Roberto from a distant thread about Chopin's third etude:"The metronome indication of the étude op.10 nr 3 in the first original edition "Maurice Schlesinger" (who is buryd near Chopin in "Pére la Chaise"...) is exactly 100 for a eight note. That meanse exactly "76" on the contempory metronome...because Chopin's metronome dit not have the same "speed"...The étude op.10 nr 2 has "144" , that means with us "116"; I think this is very important to know the exactly tempo of each étude because it's changing the 'interpretation.' "Thus, recordings at tempo 60 are rare because most resepct the author's intentions. However, the closest recording I have (among about 6) is Sgouros who clocks it in at 3:16.
have you heard the katsaris recordings? i think he gets about as close as possible to them
Consider Talsma's theory:https://www.tempogiusto.de/english.htmhttps://www.tempogiusto.de/https://www.hodie-world.com/https://www.tempusfoundation.org/https://www.wellermusik.de/ <---- best site, but only in german He compares the metronome marking of Alkan's "Chemin de Fer” with real trains of that time for example: (half note 112<->~50 km/h)https://www.digitalaudioguide.com/cgi-bin/review/music_reviewview.pl?category=classical&name=music&product=23
i wonder which hamelin considers to be the most difficult
For a master like him, nothing he cannot play.
im thinking of works that havent yet ever been recorded at the marked tempofamous ones include -hammerklavierwinterwind etudevarious alkan piecesany others?
The winterwind in the Godowksy Paraphase is probably the one that is unacheivable.
i would reserve judgement until i see the libetta tapes
