| 20090188373 | MARCHING PERCUSSIONIST PRACTICE PAD WITH STRUCTURE THAT EMULATES A DRUM - Improvements in a drum practice pad are disclosed. The practice pad is intended for use with a mobile or shoulder mounted percussion instrument carrier or with a stand configured for use with a percussion instrument. The practice pad incorporates most or all of the geometry of a drum that is addressed by a player. This geometry includes a portion of the striking surface, and a portion of the drum rim. The sticking surface is adjustable within the portion of the drum rim to match the central playing area and the height of the playing surface to the rim of the drum. The assembly allows for attachment or mounting and use of a practice pad from a third party. The strike location of the practice pad is adjustable to simulate different diameter drums. The incorporation of the drum rim allows players to practice rim shots. | 07-30-2009 |
