From the Super Mario Wiki
Trombone Tremor is a musical attack learned by Lanky Kong in Donkey Kong 64. As with all other instruments in the game, Lanky can purchase the move from Candy Kong in her shop, and when used, it destroys all enemies in the area. When used on a trombone Music Pad, it can also be used to solve puzzles. After Lanky finishes playing his trombone, the DK airwaves (also shared with Donkey Kong and Chunky Kong) surround the whole area.
