Why do the audience stand in messiah?

The audience stands during the "Hallelujah" chorus in Handel's "Messiah" as a sign of respect and reverence. This tradition is often attributed to King George II, who reportedly stood during the chorus at its London premiere in 1743, prompting the audience to follow suit. Standing is a way for listeners to engage more deeply with the music and to honor its spiritual significance. It has since become a customary practice in performances of the oratorio.
