The melody is the Bridal Chorus from Richard Wagner's 1850 opera Lohengrin, and it became the default wedding march after it was played at royal weddings in the late 1850s, including the marriage of Queen Victoria's daughter. For more than a century it has signalled 'the bride is coming' in films, cartoons and ceremonies around the world. The Thai title on the original upload simply means 'bride song', which shows how universally the tune is recognised. It remains the go-to audio cue for both sincere wedding edits and parody entrances online.
