Abstract: A guitar aid enables a user to selectively position and control tension and angle of a guitar pick for a richer sound with decreased strain on the user's hand and fingers. The guitar aid includes a band that can be adjustably sized to fit a user's finger. A guitar pick can be coupled directly to the band. The guitar pick can define a raised portion or ridge on the upper surface of the pick that serves as a first engagement feature for a first user finger, such as the user's thumb. The lower surface of the pick can include at least one outwardly projecting rib that serves as a second engagement feature for a second user finger, such as the user's index finger. The positioning of the pick with respect to the ring and the pair of engagement features cause a user to hold the pick at the proper angle and with appropriate tension when playing a guitar or other stringed instrument.

Abstract: A hitting device for cajon includes a base having a cajon hitting assembly, a shaft, and a driving portion assembled thereon. When the treading portion is treaded, the first end of the bar member is pivoted about the pivoting portion, so that the bar member drives the driving member to move longitudinally and the arm drives the shaft to rotate along a direction where the cajon hitter moves forward the hitting surface of the cajon.

Abstract: A method and devices for changing and dampening guitar strings are disclosed. The string changing device comprises a flexible urethane foam having trapezoidal sides so that the front face of the device can be inserted into the space between the Bigsby tailpiece and a front face of a guitar to temporarily hold at least one eyelet of a guitar string onto a pin of the Bigsby tailpiece while a guitar string installer is installing a string on a headstock tuning peg.

Abstract: A cymbal mounting assembly that has a housing with a through hole. A mounting rod of a cymbal stand is to be conducted through the through hole with therebeing a loose fit between the mounting rod and the housing. A cymbal is loosely mounted on the housing so it can freely pivot or rock. The assembly includes a tightening nut with a friction feature included to adjust the amount of clamping force being applied to the cymbal. This friction feature prevents unauthorized adjusting of the rocking or pivoting motion (action) of the cymbal and this preselected amount of action by the drummer is maintained even when the cymbal is placed in storage when the drummer moves to another playing location and is only changed when the drummer decides to do so. The assembly may also include a centering clip within the through that prevents the housing from contacting the mounting rod in the area of the upper portion of the assembly.

Abstract: A three-in-one drum includes a drum chamber, a drum skin and pressing rings. A beating tray is vertically and adjustably disposed in the drum chamber and covered with a cushion. The bottom of the beating tray has a microphone vibrator connected to a loudspeaker box. When the adjusting rod is rotated clockwise, the beating tray rises and the cushion is close to the drum skin. The drum skin does not ground when being beaten, this is the mute drum function. An beating trigger connected with an electronic sound source sends electronic signal to perform the electric drum function. The microphone vibrator amplifies the audio frequency signal to perform the audio amplification function. When the adjusting rod is rotated counter clockwise, the beating tray is lowered and the cushion is located away from the drum skin which sounds when being beaten to perform the raw sound drum function.

Abstract: A clamp includes a flexible, interior conical component in contact with a barrel and a rigid, exterior conical component in contact with the interior component. The interior component has a longitudinal cut over its entire length and has, at the part that contacts the barrel, two central recesses. The exterior component acts on the interior component, and has the same conicity as the interior component. The exterior component prevents unwanted opening of the interior component by exerting a pressure on the interior component. Both components have a central recess, which form, as a whole, a mouthpiece resonating box that provides greater sound volume and different timbres, depending on the size of the recess and on the material from which it is produced. The flexibility of the interior component prevents breaking of the barrel even though three interior rings thereof are placed in different planes.

Abstract: A stand and cradle suitable for resting a bass or cello instrument upon a floor includes an angled base forming a back support and C-bout support upon which a bass or cello may be rested. The base is further supported by a pivotally coupled angled support which maintains the angle of incline of the base. In one embodiment, a pair of generally planar wood members are used to fabricated the base and angled support. In an alternative embodiment, the base is formed of a pair of tubular legs pivotally joined to together with a pivotally secured angle support also formed of a tubular member. In each embodiment, the cradle and base support is foldable to a collapsed configuration for easy storage and transport.

Abstract: A percussion instrument holder that allows attachment to a user mounted carrier. The holder allows adjustment for positioning about the user, and pivoting of the holder to allow the holder to pivot or rotate up to allow the holder with instruments to fit a narrower space. The holder further allows for pivotal attachment of individual drums to link or pivot allowing the linked drums to articulate. The holder can also consist of members that allow a connected drum to move in horizontal position, angle, or height of the drum. A plurality of unique drum connecting members is disclosed that allow the connecting members to connect onto drum tension rods or on a drum lug. The plurality of connecting members can be fabricated from multiple pieces that can interconnectably be locked into position.

Abstract: A stringed instrument plectrum cover that includes a formed structure having a conformal shape adapted to match the tear-drop shape of an instrument pick. The cover comprises a thickened member having an open interior. The plucking end of the pick is exposed while the body of the pick is retained within the thickened member, whereby the member increases the thickness of the pick and improves purchase thereof. The surface of the cover includes decorative features such as phosphorescent decals and designs thereon for personalization and for identification of the pick in low light. The pick is inserted through the open end of the thickened member, whereby the pick is supported within a channel in the padded member while its plucking end and its body section is exposed.

Abstract: A tunable bridge for a string musical instrument is provided to enable a user to rapidly switch between two pre-selected string tunings simply by movement of an actuator arm. The actuator arm controls the position of a cam roller assembly, which in turn controls the pivotal movement of a rocker arm between a lower position and an upper position. A multiplicity of string fingers are mounted for pivotable movement between respective first and second tuning positions. A plurality of manually-adjustable tuning screws with engagement tips are threadedly disposed in the rocker arm. Each engagement tip is configured to press against a respective string finger when the rocker arm is placed in its upper position, thereby further stretching the strings attached to the respective string fingers and increasing their pitch in accordance with the second pre-selected tuning. Mounting of the tunable bridge does not require permanent modification of the string instrument.

Abstract: A capo for an instrument having a plurality of strings elevated above a fretboard such as a dobro, slide guitar, Hawaiian guitar, or similar raised stringed instrument. This capo uses a sliding wedge adjuster that is installed in the upper milled slot of bar member. The sliding link assembly is installed thru the sliding wedge adjuster slot, into the hole in the center of bar member aligned properly. The string tension bar is installed in sliding link assembly hole and cushion tubes are installed on tension rod, each side of sliding link assembly. The sliding wedge adjuster raises the sliding link assembly as sliding wedge adjuster is pushed inward into bar member. This action compresses the strings to bottom of bar member. This sliding wedge function is unique to this improved capo.
