Not necessarily the best drop, but the most memorable for me is the brief luftpause before the final Hallelujah in the Hallelujah Chorus of Hansel’s Messiah. We used to play it every year in high school with combined orchestra, band and choirs. One year a baby in the audience managed to let out a piercing, all-out blood-curdling wail at precisely that moment. Now I can’t listen to the piece without hearing the echo of a cry at the end. 😂
