Welcome to the Harmonic Piano Pedal Channel by Paul Barton. Martha Argerich on the harmonic pedal: It is here, at La Roque d'Anthéron, my dear collegue Georges Pludermacher, has shown me your wonderful and most interesting invention which really enriches our old piano and enables so many possibilities, as in the old repertoire and for the future. Thank you for this beautiful pédale harmonique. I wish, as do many other of my colleges young and old, to really be able to play and study with your great gift, present to the world of the piano.
