Professional pianist do harder pieces than wild jagd in two weeks. Mei-ting sun, who is only 22-23 or something like that, learned feux-follet in two weeks, wich is WAY harder than wild jagd. But I agree they're all pretty hard. Again I'm sure you'll say : "but you said wild jagd was easy" ! NO, I said i found it easier than the others, not an easy piece. And I said too I was reading it when I found it easier than the other TEs, so I could be wrong since I can't sight read that at full speed. Maybe at full speed its harder... but just at sight read to try it and to overview the difficulties, it's easier than the other TEs.
