Why would they not practise the Sonatina over and over until it is correct? I would...Ed
it is precisely because a Mozart sonata does not test double-note technique that one should practise double- note studies.While Ashkenazy may not practise exercises now, and may derive most of his technique from pieces, I doubt that he did not do or master his fair share of scales, arpeggios, and etudes as a young student.
Firstly, with regard to the initial point - ?
I have met Ashkenazy and I also know one of his very best friends,Ed
i used to really like the argument, "what piece of music is ever going to have THIS in it?"then i discovered liszt.
Good for you all who do not require technical exercises. I am truly proud of you all!
