An instructional method of an electronic keyboard includes: obtaining a playing script, wherein the playing script is generated by a first terminal or a cloud server according to a first signal generated by a recording electronic keyboard and a time point of receiving the first signal, and the playing script is configured to indicate a corresponding relationship between to-be-pressed first keys and time points of pressing the to-be-pressed first keys; and controlling indicator lights on the first keys of the instructional electronic keyboard to be turned on or off according to the playing script. In this way, a user can be prompted to press the keys through the indicator lights on the electronic keyboard, which aids the user in learning how to play the electronic keyboard.

A covering element for covering an LED installed in a planar device surface, comprising a one- or multipart emitting body as well as a circumferential fastening web connected to the one- or multipart emitting body, wherein a receiving space is formed between the fastening web and the emitting body, into which an LED projecting over the device surface can dip.

An electronic switch for the upgrade of an electric stringed instrument for enhancing the musical or artistic performance of a user. The electronic switch has two parts. The first part consisting of a printed circuit board with terminals for wire connections. On the printed circuit board are solid state relays and other electronic components. They are electronically controlled by the second part that is an external user-controlled switch. The switch is an LED touch capacitance switch, also referred as but not limited to, a capacitance touch switch, or touch key. The capacitance touch switch has an LED light that changes colors from either a blue or green to red, but not limited to, indicating when the electronic switch is activated. When the LED touch capacitance switch activates the electronic switch board, the electronic switch board reroutes multiple signals that are attached to its terminal connectors. The electronic switch allows the user to route multiple signals at once with one touch of the LED touch capacitance switch. The LED touch capacitance switch consisting of an LED light that changes colors from either a blue or green to red, but not limited to, when touched allows the user to know the status of the electronic switch. Both parts of the electronic switch obtain power from some type of battery or super capacitor power source, but not limited to.

The present invention is a guitar control system, with level indicators, and an application for an electronic device. The guitar control system may be retrofitted to already existing guitar rig components, or the guitar control system may be integrated into new guitar rig components. The level indicator contains multiple LED lights that light up to show where to position knobs on the guitar rig component to achieve a desired tone. The desired tone may be saved by a user, or the desired tone may be downloaded from a database of existing tones.

An embodiment of the present disclosure provides a portable electronic musical instilment, including a press module, a control module, an angle detection module, and an audio play module; the press module is arranged above the control module; the angle detection module and the audio play module are respectively connected to the control module; the angle detection module is configured to detect a rotating angle of a portable electronic musical instrument body; the control module is configured to adjust, according to the rotating angle detected by the angle detection module, different registers; the press module is configured to receive a press event of a user; and the audio play module is controlled by the control module to play tones of different musical scales.

In one aspect, provided herein is a device for notating a musical composition. The device, in various implementations, is structured so as to be less laborious to notate, easier to read, and more simple to employ in notating, reading, and/or playing the music of a given composition to be composed and/or played. Accordingly, in its most basic form, the device herein disclosed includes a template, upon which template one or more symbols may be notated, where such notation is configured in a manner that more closely relates the note to be played with the mechanical action needed to be performed so as to play that note, such as on an instrument to be or being played.

A method, system and associate peripheral device for remotely teaching piano. The device (13/23) comprises a plurality of indicator LEDs along its length for arrangement/alignment across a student piano keyboard (11). When a key is triggered on a remote piano keyboard (21), e.g., by a teacher, one of the LEDs lights up at the equivalent key at the student piano keyboard. The system also allows for playing notes from the student or teacher piano keyboard, communicated over the internet, at the teacher or student piano keyboard and vice versa.

A setting device includes an operating element and a light-emitting device. The operating element is used for specifying a setting value of a first parameter by moving the operating element within a first region. The light-emitting device includes a second region that is disposed inside the first region. The second region includes a light-emitting area that changes according to the setting value. The operating element covers part of the second region. The operating element is an operating element for specifying a setting value of a first parameter related to sound by moving the operating element relative to a housing. The operating element includes a first portion and a second portion. The first portion blocks light. The second portion transmits light from a first surface of the operating element to a second surface facing the first surface.
