That wouldn't be nice... I've never heard that man can be strained because of weeping a piano piece... I didn't know that this is possible

And may I ask you a question of tecjnical nature? Are is is possible to weep chords an several voices? In "Für Elise" his shouldn't be the main problem but I think if you want to weep something like the "Waldstein" you might got some small difficulties...
But I look forward for your development from a pianist to a professional weeper of classical music
