About Guillermo Helguera, Samuel Máynez says: “He was my dear master, from whom I could say I learned most of what I know as a cello player, and he left me, without any reservation, all the technical knowledge he had acquired from the great cellist Janos Starker. For him, with my eternal gratitude, I dedicate this study about the technique and themes of string changes, which I admired so much in him, since he could master it all like nobody else, with a really surprising dexterity.” A “perpetuum mobile’ made of a succession of harmonic beats, where one has to follow a strike of 3 linked notes, played up (pushed), compensating them with 3 light notes played down (pulled). This bow strike, far from being conventional, called, according to various musicians, flying staccato
, or ricochet
, was used often by the composer L. Boccherini. This study aims specifically at perfecting the high-speed change of strings, opening and closing the arm with the bow, working all the while on the elbow. The short bouncing of this bow strike gives the string instruments a peculiar air of freshness.
