Although a number of melodies may be suitable music for weddings, there are two in particular from the world of classical music which are most frequently played. One is the Wedding March by Mendelssohn which is the incidental music to A Midsummer Night's Dream. It became customary to play at marriage ceremonies from about the mid 19th Century.

The other is the Bridal Chorus by Richard Wagner. This is associated with weddings because it is used in his opera Lohengrin at the marriage between the title character and Elsa.

Here comes the bride, all fat and wide
Doesn't she wiggle from side to side
Here comes the bride, all fat and wide
Ten pounds of mince meat walking by his side

Guided by us, thrice happy pair
Enter this doorway, 'tis love that unites
All that is brave, all that is fair
Love now triumphant forever unites
Champion of virtue boldly advance
Flower of beauty gently advance

Here comes the bride, all dressed in white
Sweetly, serenly in the soft glowing light
Lovely to see, marching to thee
Sweet love united for eternity
