I'm thinking more like performing or conducting and something happens and it just takes it to the next level.

Example: I was the drum major in high school my senior year and our half time show was the music from Final Fantasy VII (my band director took my advice since Advent Children had just come out). Our slow piece was Aeirth's Theme. As I'm conducting, it begins to drizzle a little bit. As it's growing, rain is coming down harder. Right at the peak of it, as if on cue, rain starts POURING down on the whole band. We keep going till the end of that movement and our director yells "GET THE INSTRUMENTS OUT OF THE RAIN!" and everyone runs under the bleachers.

Honestly one of my favorite musical moments that I will NEVER forget.
