The wedding march has been a staple of wedding ceremonies for well over a century, with its bright, processional melody making it instantly recognisable even to people who have never attended a formal ceremony. In online videos, the piano version is especially popular because it sounds clean, light, and easy to layer under speech or captions without overpowering a scene. Creators keep returning to it for engagements, anniversaries, and joke weddings because the tune alone tells the audience exactly what kind of moment they are watching.
