Abstract
A harmonica has a reed plate with a plurality of reeds overlying slots in the plate. The reed plate is mounted in a chamber of a housing, and the harmonica is played by forcing air from the player's mouth through passages in the housing and past the reeds. If a reed becomes separated from the plate, it is trapped in the chamber. This prevents a separated reed from travelling along the passages into the mouth of the player and possibly injuring the player.
