Hubay, hungarian composer, wrote much music based on the folklore of his own country, and also of the gipsies... For that particular piece, He asked the collaboration of a true Gipsy : Aghazzi, to enable him to write exactly those very peculiar types of runs used on the cymbalum... a sort of open grand piano (rather piano-forte) without keyboard, and played by knocking the strings directly with sticks like for on a xylophon... The only trick is that the strings unlike the piano, are not range from low to high pitch, but in a way that even if it ressembles to disorder, is in fact very complex, and permits in just playing the strings in a row to get proper gipsy's arpegio formulas... That was recorded in concert in a French castle, by Jean-Claude Féret and Christine Hartley-Troskie...

But, unfortunately for the moment, the texts are still only in French (but music goes over that border isn't it !).
