CLASSICA JAPAN TV 'Yuko Kawai talks about Chopin National Edition'
- Vol.4b "The most 'shocking' difference in Chopin's editions - Let's see the sources" (Excerpt)
Gutmann didn't write a repeat/repetition sign (just double barline) but First German Edition put it receiving/using Gutmann's copy. Why? Yuko checked it at National Library in Warsaw. Gutmann's copy - on the second page of the first movement - the theme is 'thicker' with the accord, there are more notes. One of the right hand's notes from the second page - the ink has run to the reverse side, to the first page - near the 5th bar. But one dot, not two. Then First German Edition put a repeat/repetition sign and published. Pianists all over the world started to play wrong(ly). What a history...
played/showed Chopin Sonata in B-flat minor Op.35, the 1st movement (fragment)
And from Yuko's CD: Chopinissimo I (Imagine)
Yuko expresses her greatest and deepest respect for the work by prof.Jan Ekier and prof.Paweł Kamiński.
