摘要:
An adaptive equipment for playing chords on a musical instrument is provided. The apparatus can have a shell having an interior cavity. The adaptive equipment has a root pin partially installed within a root housing channel of a root housing, the root housing is fixedly installed within an interior cavity of the shell and is positioned toward the left side of the shell. The adaptive equipment has a fifth pin partially installed within a fifth housing channel of a fifth housing, the fifth housing is fixedly installed within the interior cavity of the shell and is positioned toward the right side of the shell. The adaptive equipment has a third pin partially installed within a third housing channel of a third housing, the third housing is movably installed within the interior cavity of the shell and is positioned between the root housing and the fifth housing. The root pin, the third pin and the fifth pin correspond to a major triad on a piano keyboard when the third housing is positioned closer to the fifth housing. The root pin, the third pin and the fifth pin correspond to a minor triad on the piano keyboard when the third housing is positioned closer to the root housing.

In one embodiment, a method for the enhanced display of the hands of a pianist playing a piano is disclosed, including: (a) recording at least one video stream of at least one hand of a pianist playing a piano; and (b) while the pianist is playing the piano, using at least a portion of the piano as a display for displaying the video stream.
摘要:
A piano (1) having a dense sound-enhancing component (2), said piano (1) having a case (6), a frame (3) located within the case (6), strings (5) located within the frame (3), keys (9) in connection with hammers (11), two bridges (13) each of stone having a top face (27), a bottom face (28), a first side (29) and a second side (30), bridge pins (16) extending from the top face (27) at an angle, the strings (5) extending across the bridges (13) adjacent to the bridge pins (16), a soundboard (4) and an amount of epoxy (18) located between the bridges (13) and soundboard (4). The dense sound-enhancing component (2) is a stone material, preferably granite, and enhances the sound of the piano (1) by holding and sustaining pitch longer, providing a longer and stronger signal, providing a higher volume or decibel level and having a decreased decibel fall-off as compared to conventional pianos utilizing wood bridge(s).

An action mechanism of a mechanical piano including a wippen accommodated on a wippen rail, a repetition lever with a flange, a jack, a hammer, and a pair of permanent magnets arranged so as to repel each other. The first magnet is attached to the wippen and the second magnet is attached to immovable structure of the piano.
摘要:
An upright keyboard musical instrument has an open/close board attached to the top position of a case, wherein the lower surface of the open/close board is subjected to mirror surface finishing and is supported by a lid prop, which is rotatably arranged in proximity to the top board to rotate about a support axis and is formed in an L-shape to have a plurality of support surfaces, realizing different angles for the open/close board being opened. The mirror surface of the open/close board projects images representing internal members of the case, such as an emblem and actions. By appropriately rotating the lid prop, it is possible to realize a desired angle for the open/close board, thus realizing tone volume control and visually entertaining effects in musical performance.
摘要:
A safety device used on pianos to prevent the slamming of keyboard lid. Present invention uses a suction cup with a rod that can be folded down, so that it takes up very limited room, when it rod is down. When in use, if the piano keyboard lid is tilted towards the closing position, a rubber roller on top of the rod will contact the inner surface of the lid and stop the falling motion, preventing injuries to piano player's hand or fingers. The inner 90-degree angle of the lid will serve as a catch-well for the rubber roller to prop up the lid.
摘要:
A steel wire (e.g., a piano wire) for use in a stringed musical instrument is designed to have a specific chemical composition in which phosphorus content ranges from 0.015 weight percent to 0.050 weight percent, wherein the total decarburized layer depth of a decarburized layer formed on the surface, which is subjected to decarburized depth measurement using a microscope method as defined in the Japanese Industrial Standard JIS G 0588, is reduced to 2 μm or less. Other chemical substances included in the chemical composition of the steel wire are preferably defined in the standard JIS G 3502 regarding chemical compositions of piano wires. In manufacturing, a rolled steel material is subjected to wire drawing and patenting under prescribed conditions, wherein the sound quality realized by the steel wire installed in a stringed musical instrument can be noticeably improved by adopting both chemical composition control and total decarburized layer depth control.
