Die Blaue Mazur (The Blue Mazurka) was a celebrated success for Franz Lehár after its premiere. Musically it is one of his greatest masterpieces. The Successful factors were, firstly, the libretto’s humorous vein; secondly, the mixture of musical styles; and thirdly the dramaturgical role played by dance. The opera is light hearted even in dramatic passages and is peppered throughout by waltzes, dances, the mazurka and the three large scale finales.
