A counterhoop formed by bonding a conventional flat shaped hoop with a resilient shell component comprised of a convex outer wall and a generally flat inner wall. The resilient begins as a liquid resin, which is poured into an annular mold. The metal counterhoop is inserted into the resin, and the cured resin is allowed to harden, forming a shell which is bonded to the counterhoop to create a unitary component. The inner and outer walls of the shell join at the top edge of the counterhoop, where…

A percussive instrument comprises two shells, each having open ends. The shells are positioned substantially end to end. Drum heads are positioned at the opposing open ends and between the two shells.

A system for adapting a tracker bar operated automatic musical instrument to play electronically stored performances includes, in one embodiment family, a channel plate member having parallel channels in the upper face. First and second spaced apart holes are provided in each channel. An array of solenoid operated valves individually open and close first holes in the channels in response to energizing signals selectively applied to the solenoid coils. The second holes are oriented to interface w…

The present invention provides a unique device for protecting the strings of musical instruments such as guitars and stringed bases in the event they should topple over face down. The device also serves to clean and buff the strings of musical instruments while at the same time providing a pocket 14 and 15 for pick storage. The present invention is a pad 12 of soft cloth or pre-formed soft rubber which when attached to the strings of musical instruments will not scratch and damage the instrument…

This invention is a display system for measuring and displaying, individually or simultaneously, the frequencies contained in a musical sound. A transducer coupled to the sound source produces an electrical signal representing the musical sound. The system receives the signal and separates and measures the frequencies of the individual tones comprising the sound. The measured frequency values are displayed as the frequencies themselves or as deviations from target frequencies. The system can uti…

A musical instrument made in whole or in part of titanium and its alloys. Titanium instruments tend to be lighter than other instruments made of other materials like silver and/or gold. Additionally, titanium proves to be more durable and resistant to marring than other materials used in making instruments. An inherent property of titanium provides the ability to create an infinite number of color hues and patterns of colors on the instrument by the use of known titanium anodization processes. A…

This invention relates to the field of electrical technology, and relates particularly to a method for the continuous transformation of electrical energy with its subsequent transmission from an initial source (transformer) to a consuming device, and also to an apparatus for the implementation of this method of transformation and the supplying of power to electrical devices through a transmission line which does not form a closed circuit, ie consists of a single conducting wire. This invention t…

An electronic percussion instrument includes a pad section and a rim section provided about the pad section. A pad sensor is provided in the pad section to output a signal in response to a force applied to the pad section. A rim sensor is provided in the rim section to detect a signal corresponding to a force applied to the rim section, for example, to detect the presence or the absence of a pressure force applied to the rim section. The electronic percussion instrument includes a tone generatio…

A computerized music apparatus is installed with a program which is executed to perform reproduction of a musical tone by reading out a corresponding waveform. A storage is provided for storing a plurality of waveforms corresponding to different musical tones, each waveform being stored in the form of a sequence of amplitude value data arranged at a given sampling period. Tapping pads are provided for designating at least one of the stored waveforms to command reproduction of a corresponding one…

The three dimensional probe device of the present invention is mountable on a working end of a fully automated and articulated robotic arm movable through at least five degrees of axial freedom in a global dimensional reference. The three dimensional probe device comprises a base, a carriage, a probe, a Z axis measuring apparatus and a tilt measuring apparatus. The probe tip contacts the work piece surface to be traced with deflections in the workpiece seam or path resulting in movement of the c…
