Felix Mendelssohn's "Wedding March" is one of the best known pieces from his suite of incidental music (Op. 61) to Shakespeare's play A Midsummer Night's Dream. It is one of the most frequently used wedding marches, generally being played on a church pipe organ.
It is commonly performed as the bridal party files out at the end of the service. It is frequently teamed with Richard Wagner's "Here Comes the Bride."
