The polka-mazurka was not credited to the Strauss family alone as many Viennese composers in the 1850s era also wrote many examples. This variant of the polka was seen as cross-cultural, as many of its influences can be seen in the French-polka with its feminine and deliberate steps as well as the exciting schnell-polka where Eduard Strauss composed many famous pieces of this type.
The polka-mazurka does possess a similar structure to the polka, with a main theme quickly proceeding to its subsidiary theme which is usually brash and loudly played. The 'trio' section is free-style and need not associate with the main theme nor of the same key signature. The Strauss family; Josef Strauss in particular, attempted in most of his famous polka-mazurkas to blend in sensitivity and romanticism as can be heard in his pieces Sympathie op. 73 and Frauenherz op. 166 which were inspired by his concern for social issues faced by women in that by-gone era.
