A portable drum kit is disclosed. The disclosed drum kit comprising a base; musical instruments comprising one or more drums and at least one cymbal to be fitted on the base; one or more vertical columns fixed to the base to support at least one of the musical instruments at; one or more rod members detachably coupled to the one or more musical instruments; and at least one pair of modular clamps adapted to enable fitment of the least one of the one or more drums and the at least one cymbal to the vertical columns. The modular clamps allow movement of the musical instruments between an collapsed position in which the drums and the cymbal are placed closer to each other, and a deployed position in which the drums and the cymbal are placed at desired positions to allow a percussionist to use the drum kit.

An acoustic shield system is described that is suitable for musical performances. In one example, a side wall is configured to surround a portion of an edge of a cymbal opposite a percussionist to reflect sound back toward the cymbal and toward the percussionist. The side wall has a top edge above the cymbal and a bottom edge below the cymbal. A substantially flat top plate is attached to the top edge of the side wall and extends from the side wall over and across the center of the cymbal. A substantially flat bottom plate is attached to the bottom edge of the side wall and extends from the side wall under and across the center of the cymbal. The bottom plate is parallel to the top plate. The bottom plate and the top plate are spaced to accommodate regular movement of the cymbal when struck.

A drum set comprising a cajon, a convertible top module and a convertible bottom module is provided. The cajon can have a top side, a bottom side, a striking side, an opposing resonant side, and two other sides. The top module can include a top mounting member removably attached over the top side of the cajon, the top mounting member has at least two top clamps configured to clamp at least two sides of the cajon. The top module also has a plurality of upward extending component mounting shafts removably attached to the top mounting member. The top module has one or more percussion modules configured to removably attach to one or more of the plurality of component mounting shafts. The bottom module can include a bottom mounting member removably attached under the bottom side of the cajon. The bottom mounting member has at least two bottom clamps configured to clamp at least two sides of the cajon. A drum kick assembly can be removably attached to the bottom mounting member and positioned on the striking side of the cajon and including a beater positioned to strike the striking side of the cajon to produce a sound. A hi-hat pedal assembly can be removably attached to the bottom mounting member and positioned on the resonant side of the cajon.

An electronic hi-hat 1 has a rod movable up and down with an operation of a player. A top cymbal 2 has a striking surface that can be struck by the player. A bottom cymbal 3 comes into contact with or separates from the top cymbal 2. An optical sensor 7 detects separation dimension between the top cymbal 2 and the bottom cymbal 3. The optical sensor 7 detects separation dimensions of a plurality of areas that are displaced with inclinations of the top cymbal 2 and the bottom cymbal 3 with respect to the rod r. The plurality of areas where the separation dimensions are detected are located on a common circumference of the top cymbal 2 and the bottom cymbal 3 around the rod r as a center.
