One is Mendelssohn's wedding March. Mendelssohn's work, originally the prelude to the fifth act of the opera A Midsummer Night's Dream, was completed at the age of 17. It was originally the piano prelude to Shakespeare's play of the same name, and it was loved by the world because of its wonderful fantasy and romantic interest. Later the composer adapted it into a band work.

One is Wagner's wedding March. The Wedding Chorus, which was originally the mixed chorus at the beginning of the third act of the opera Lohengreen, was named the Wedding March because it was often used as wedding music, and was later adapted into orchestra.

The former is cheerful and enthusiastic, while the latter is solemn.

According to western tradition, the bride will play Wagner's Wedding March when she enters the venue. When the couple walk out of the church, they will play Mendelssohn's wedding March.
