Nikolai Kapustin ： Five Etudes in Different Intervals Animato: Etude in thirds and sixths Op.68-3

Built around the intervals of thirds and sixths, this etude brings its Animato character—lively and animated—to the forefront. The succession of intervals demands finger independence and precise leaps while generating a sense of momentum that goes beyond purely mechanical practice. A key to performance is distinguishing the exchange of figures and changes in sonority while maintaining the overall flow. First, aim to align each interval without strain, creating light, agile movement without stiffening the wrists or arms. Attention to dynamic contours and phrase direction brings musical coherence to its sharply defined sense of motion.
