ABSTRACT:
A snare drum strainer mountable to the shell of a drum comprises a piston and an actuator. The piston has an axis and a surface curved about an axis generally parallel to the piston axis, and the piston is operatively connected to snares. The actuator and the curved surface rotate one with respect to the other about an axis generally parallel to the piston axis to reciprocate the piston and to tension and untension the snares. In another embodiment, the piston includes a generally cylindrical surface with a generally helical groove, the piston is operatively connected to snares, and the actuator includes a follower insertable into the generally helical groove. The follower and the generally cylindrical surface rotate one with respect to the other to reciprocate the piston and tension and untension the snares.
