The interval of a sixth is a very prominent interval in piano performance; when it appears, consider it a special interval that demands more attention than thirds or fourths.

Fundamentally, when playing a sixth with the right hand, the inner voice is almost invariably played by finger 1 or 2, and the outer voice by finger 4 or 5. As finger 1 is the strongest and fingers 4 and 5 are weaker, this interval naturally tends to make the inner voice more prominent than the outer voice. This is a crucial point not only for this piece but for all piano pieces in which a sixth appears.

In this Polonaise, the primary aim is to play the outer voice clearly and the inner voice softly. From measure 4 onwards, thirds also appear; for these, too, ensure the top voice is brought out as much as possible.

The middle section, or B section, modulates to B-flat major and should become slightly softer. However, it also features thirds in the left hand and sixths in the right hand. Play the middle section as leggiero as possible, and again, bring out the top voice.
