In 3/8 time. Oberek is one of Poland's folk dances, a spirited dance characterized by a rapid tempo, vigorous spinning and running in circles. It is typically written in 3/8 time, and its basic rhythmic pattern combines eighth notes and quarter notes, often described as 'ta-ta-tan-tan,' though successions of shorter note values, such as sixteenth notes, are also common. The repeated G notes in the opening four measures should be played with an awareness of the accent on the first beat, to establish a strong sense of meter from the beginning. From measure 5, in addition to the swirling melody in the right hand, be mindful of the augmented intervals in the left hand, and strive to maintain the triple meter throughout your performance. From measure 21, while maintaining the momentum, try to shift the atmosphere slightly and enjoy the intriguing harmonies.
