Abstract: An arrangement for enabling facile and efficient operation of at least one bass drum mallet, in combination with at least one bass drum, such that the bass drum with its associated mallet can be placed in any desired location, within and beyond, a limited Critical Performance Area which is encountered with conventional drumming equipment, and such that the mallet is operable by means of at least one foot pedal, placed close to, or remote from, the location of the mallet/bass drum assembly. The arrangement offers considerable flexibility in the location of bass drums and other drum/musical instruments, and equipment, and can be operated by means of wire, wireless, or direct mechanical, communication between the foot pedal and the bass drum mallet.
