Rhythm played a fundamental role in “Tango Ostinato.” As implied by the title, an ostinato pattern in the left hand gives this piece its distinct quality. Quality of sound and consistency of attack are extremely important for keeping this accompaniment pattern engaging. Dynamics also play a crucial role. The entire piece has an underlying tension of loud dynamics trying to overpower the original pianissimo. Perhaps the dramatic side of the piece wins, since the final measures are to be played fortissimo.
