• wherein said tuning structure includes:
• a tuning plate mounted on said shaft, said cymbal plate having an upper surface, said tuning plate being in contact with said cymbal plate;
• and
• an arm assembly mounted on said shaft, said arm assembly defining a plurality of spaced apart arm members which extend radially from said shaft, each arm member of said arm members having a free outer end, each said free outer end being in contact with said tuning plate and the pitch of the sound is determined by the contactual pressure of said free outer ends on said tuning plate which is transferred to said cymbal plate.
