I do not understand how people are able to play the trombone. In order to play the correct note, the slide has to be positioned in exactly the right spot, and is constantly moving in order to play a complicated song. There is no marking for the notes, so you have to memorize their location, and have lots of arm strength to play for an extended period of time.
As per usual, I have invented a fantastic solution to the problem presented. Inspired by the moving ink thing in printers, the Automatic Trombone-Playing Machine is programmable, and moves quickly and precisely into the correct positions. A keyboard conveniently attached to the instrument allows the slide to be moved at the press of a button.
