Felix Mendelssohn composed the Wedding March in 1842 as part of his incidental music for Shakespeare's A Midsummer Night's Dream, and it soon became one of the most recognisable wedding processionals in the Western world. Its association with grand entrances and celebrations made it an easy fit for live streaming, where Portuguese-speaking creators adopted the opening bars as an alert for the largest donation of a broadcast. The contrast between a formal wedding tune and a casual chat moment keeps the gag fresh, so the clip continues to circulate as a celebratory notification rather than just a classical excerpt.
