<p>A counter loop for a musical drum hoop includes a reinforcing channel member and preferably a reinforcing rim. The drum counter hoop retains a drum head with an associated locking member, or ring, by fastening lugs or the like secured to the drum shell and by suitable fastening means such as threaded bolts with nut-type heads thereon, sometimes referred to as tension screws, or rods, which engage with the hoop. The lugs are internally threaded or provided with extensions for threads to engage with the bolts. The drum hoop and drum shell are, therefore, provided with means for adjusting or changing the tension of the drum head by tightening or loosening the bolts which changes the position of the hoop and the drum head locking member with respect to the drum shell. The reinforced construction permits the drum head to be provided with a very high tension without bending or breaking the drum hoop. <IMAGE></p> |
