Yamaha's Singing Trumpet is apparently a huge success with Japanese men in their 40s and 50s who can't play the instrument but would love to blow the horn like musicians in old movies.

You put your mouth to the trumpet, sing to yourself, and the horn plays the tune. Twenty-two tunes are programmed into the trumpet -- including saxophone, flute, and human voice-- and
others can be downloaded for 210 yen apiece from a dedicated website.

Another exciting (!!!) option features valves that light to show you how to press the valves correctly. The guide lamps turn on accourding to the proper notes, and the accompaniment pauses until you play correctly.
