The person saying that obviously wasn't doing it correctly...!
Im an 18 year old piano student who started to play piano from scratch 4 years ago. Within 2 years, one of my competition pieces was Chopin's 3'rd Scherzo. I have won a few competitions with it and I owe my being able to play it on 1 thing and 1 thing alone: Pischna. I don't care what anyone says, I will do Pischna for the rest of my life as I am living proof that it works! I know my little story will stir some controversy as I saw a previous posting where Pischna is regarded as rubbish but all I have to say about that is: The person saying that obviously wasn't doing it correctly...!
