The first Mazurka in the set is in B-flat major and has a time signature of 3/4. It also has the tempo marking: Vivo e risoluto (Tempo:♩=160).
This Mazurka has the form of a rondo. The refrain, of unconventional design, thrusts its way upwards, swinging and swaggering, before falling back down in a delicate scherzando. The first of the two episodes, the one in F major, is a kujawiak.
