Glenn Gould said his recording of Brahms intermezzi to be "very sexy".
Well, i heard twice that Ravels "Bolero" should be very erotic. I think
it is hmm... the rythm. In my opinion, an erotic touch is mostly linked
to associations. Maybe Scryabin made erotic associations composing some
of his works. "Vers la flamme" " in direction to flame (sweetheart).
Or "Poeme dextase". Or even some Etudes....
Chopin could be played erotic. And kinky (lacking technique).
Best wishes, Norman
