What does not characterize Chopin's mazurka in b-flat minor op. 24 no. 4?

Chopin's Mazurka in B-flat minor, Op. 24 No. 4, is characterized by its lyrical melodies, rhythmic vitality, and expressive nuance, but it does not feature a strict, uniform structure or classical sonata form. Unlike more rigid classical forms, this mazurka embraces a freer, more improvisatory style that reflects Polish folk influences. Additionally, it avoids the heavy, dramatic qualities of some of Chopin's other works, instead focusing on subtle emotional expression.
