Improved endpin stand apparatus for large stringed instruments are provided. The endpin stand apparatus comprises components to elevate the endpin shaft from the floor on which the endpin stand apparatus rests, and may comprise a kickstand. The endpin stand apparatus may comprise an endpin shaft and/or a hole for receiving an endpin shaft, or may comprise a platform, which supports a large stringed instrument. The endpin stand apparatus allows for adjustment of the height of the apparatus and thus of the stringed instrument, and may allow of adjustment of the angle of the instrument relative to the axis defined by the apparatus. The apparatus allows a user to stand while playing the instrument, and to move through a forward-to-back and side-to-side range of motion. The adjustable height and angle allow for a range of instrument locations and angles, and increased range of motion by the musician while playing the instrument.

Improved endpin block apparatus for stringed instruments are provided. The endpin block apparatus comprises an endpin support for securing and connecting an endpin to a stringed instrument. The endpin block apparatus may be fixedly attached to the instrument or may be able to rotate about an attachment location, allowing for adjustment of the angle of the instrument relative to the axis defined by the endpin and the musician. The endpin block apparatus provides one or more endpin insertion locations, allowing for one or more angles of the endpin relative to the axis of the instrument, which angle may be adjustable, and may allow for more of the instrument's weight to be borne by the endpin. The adjustable endpin angle and the adjustable endpin block apparatus rotation allow for a greater range of instrument location and angle, and more support of the instrument by the endpin, removing weight from the musician.

An accessory for modifying sound output of a musical instrument. The body of the instrument has a soundboard. The accessory includes a sound sensor, an actuator, a fastener, and a controller. The sound sensor engages the body and senses vibration of the body representing the sound output of the musical instrument. The actuator engages the soundboard and deforms the soundboard of the musical instrument so as to modify the sound output of the musical instrument. The sound sensor is preferably arranged distally to the actuator. The fastener engages the accessory to the musical instrument, to locate the actuator against the soundboard of the musical instrument. The controller is connected to the actuator and the sound sensor for receiving and analysing the sound output sensed by the sound sensor, and controlling the actuator in dependence on the sound output sensed by the sound sensor.

A resonance podium includes a plurality of walls defining a frame of the resonance podium. A top panel is coupled to the plurality of walls to form a top surface that supports a performer playing a musical instrument on the resonance podium. A resonant panel is also coupled to the plurality of walls and isolated from the top panel. The resonant panel is configured to receive a portion of the musical instrument and to project structurally-transmitted vibrations from the musical instrument for acoustical amplification.

A main body fixing member is disclosed. The main body fixing member fixes an endpin including a shaft portion having a first end housed in a musical instrument main body and a second end stood on a floor. The shaft portion is provided with a recess. The main body fixing member includes a fitting portion, a through hole through which the shaft portion of the endpin extends, an opening disposed orthogonal to the through hole and having a bottom surface, a columnar member, a biasing portion, and a pressing portion. The columnar member is provided with a hole through which the shaft portion extends, and an engagement protrusion engaged with the recess of the shaft portion. The engagement protrusion is formed on an inner surface of the hole. The pressing portion presses the shaft portion inserted into the through hole and the hole via the columnar member.
