Basic Principles in Piano Playing as Taught by Josef & Rosina Lhévinne, Explained by John Browning

Outtakes from the documentary "Memories of John Browning: The Lhevinne Legacy Continues" (2006).
The American pianist John Browning (1933-2003) explains and demonstrates some principles in piano playing as they were taught by Josef & Rosina Lhévinne. At the end he plays Chopin's Nocturne In D flat major, Opus 27 no. 2.
