Gadget fits inside bugle, plays music for you.

bugleElectronic bugle implant makes it so you don't have to learn the instrument in order "play" it.
The device ... slides snugly deep into the bugle's bell. The device plays a high-quality recorded version of “Taps,” taken from the 1999 Memorial Day service at Arlington National Cemetery. The resonating tones inside the bugle create a realistic horn quality.
And here's a related article:
"Facing critical shortage of musicians for military funerals, the Pentagon has approved the use of a push-button bugle that plays taps by itself as the player holds it to his lips"

..."With a small digital recording devise inserted into each bugle's bell, a member of the honor guard at the funeral simply presses a button on the devise. A five-second delay give the guards time to raise the instrument to their lips as if they are going to play it"
