Abstract

A drum tuning key comprises a handle portion, a barrel portion defining an axis connected to the handle portion, the barrel portion having internal walls defining a cavity extending inwardly along the axis from an end of the barrel portion, the cavity being square in cross section and adapted to turn a drum tension rod. The tuning key further comprises an indicator member removably disposed on at least one of the handle portion and the barrel portion. The indicator member may comprises a single plug member removably disposed on said handle portion, or a pair of plug members disposed on opposite lateral ends of said handle portion. The plug members may be different colors, different materials, and/or different hardness to enhance the assembly and tuning operation as well as pitch adjustment.

1. A drum tuning key, comprising:

a handle portion,

a barrel portion defining an axis connected to said handle, said barrel portion having internal walls defining a cavity extending inwardly along said axis from an end of said barrel, the cavity being sized and dimensions to mate with a drum tension rod,

an indicator member removably disposed on a terminal end of said handle portion, wherein said indicator member comprises a plug member having a rounded surface that projects from said handle portion for striking a drum head, and

wherein said indicator member is chosen from a particular material different from said handle portion to facilitate testing of a pitch for said drum head.

2. The drum tuning key according to claim 1 , wherein said indicator member comprises a pair of plug members disposed on opposite lateral ends of said handle portion.
