Every clod has a silver leaning
Picture, if you will, a musician - unstable at the best of times. I can't say who it was because I don't know. I could ask an eye witness (SonOfVirge) but I'm not sure I want to know.
Now consider that this musician is in his teenage years. This is when various limbs go through spurts of growth and the ones furthest from the brain sometimes have a little trouble keeping up with instructions from mission control. Now picture this teenage musician trying to navigate through a forest of music stands, chairs and expensive instruments. If it was on film you'd expect this scene to come just after the dialog that informs us that the trumpet is uninsured.
Of course in the film we'd delay the climax for as long as possible with some near-miss foreplay. In real life it happens all too quickly: the trip, the staggering step that topples the trumpet from its stand, then the recovery step - when the other foot is brought forward to halt the falling body and plants itself directly onto the prone trumpet. It's done.
I don't think this silver was designed to be a crumple zone. It's not a write-off. SonOfVirge can still play it and the tone is not noticeably marred. It needs fixing. I know car panel beaters are renowned for their ability to charge. I dread to think what their musical counterparts are like.
