Electronic cymbal assemblies are disclosed. Assemblies according to the disclosure can include a single frame and a cover thereon, the cover including a cutout with flat edges to prevent accidental rotation of cymbal assembly components. Assemblies according to the present disclosure can also include non-planar sensors that can be applied to the bell and edge portions of a frame, sensors and frames with respective protrusions and bumps to mate with one another, and cover undersides with non-smooth surfaces to increase sensitivity to user actuation.
