Lost silver clarinet with unique engravings in a black case with initials, after a performance at Kansas City concert hall.

I lost my silver clarinet last night after leaving a performance at the Kansas City concert hall. I remember packing my bag before I left, but I can't find it anywhere. It has some unique engravings on the body and is in a black case with my initials on it. I'm really worried and just want to get it back!
