Included are: an acquisition unit (13b) configured to acquire identification information and a time-series feature regarding a signal indicating a tactile sensation, the identification information and the time-series feature being visually expressed; and a generation unit (13c) configured to generate a control signal for a tactile-sense presentation device (100) on the basis of the above identification information and the above time-series feature acquired by the acquisition unit (13b).

A system to teach mathematics using virtual musical instruments displayed on a client computing device includes a server, a database stored on the server, an application stored on the server, and a plurality of songs stored on the server. The system also includes a plurality of mathematical equations stored in the database, where each mathematical equation comprises a composite of musical notes and mathematical operators. The system includes a local application stored on the client computing device to display the virtual musical instrument and is configured to display a correct indicator in response to the user solving the mathematical equation correctly when the user plays a musical note on the virtual musical instrument corresponding to the numerical answer that correlates to the song.

An electronic device, which is an electronic musical instrument as an electronic device, includes: a rotating shaft inclined with respect to a perpendicular line of a panel; and a rotary knob that is attached to the rotating shaft and has a fingering marker portion provided opposite to an inclination direction of the rotating shaft.

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 practice apparatus includes a light source device that emits light beams in different colors to keystroke positions on a keyboard or a keystroke object with keystroke positions that imitates a keyboard, fluorescent paper pieces that are respectively attached to the fingers of a player and have different colors for different fingers, and a main device that has a storage unit for storing therein music information on music and a transmitting unit for transmitting, to the light source device, a signal relating to the colors of the light beams, which depend on the colors of the fluorescent paper pieces attached to the fingers of the player, and the timing of emitting the light beams, based on the music information stored in the storage unit.

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 musical instrument, including a chord player section having at least one chord player operable to play a selected chord, the at least one chord player including a finger-actuatable first pad having a first center point function and a plurality of first perimeter point functions. The first center point function and the plurality of first perimeter point functions are respectively operable to generate a primary chord having a chord root note or variations of the primary chord having the chord root note.

An electronic percussion device has a plurality of touch sensitive pad, an array of lighting elements disposed adjacent each pad, and a virtual display of the currently selected kit. The light array provides the user with immediate visual cue about the status and capabilities of the sound selections, without having to interrupt the user's performance. The user can color code and animate the illumination pattern of each light array so that, from a distance, the user is visually reminded what sounds are assigned to each pad, when sound associated with particular pad is currently playing, when playback of a sound associated with a pad is about to end.

An electronic percussion device has a plurality of triggerable actuators, in the form of any of pads, external trigger inputs or foot switches, that may be organized into synchronized groups, and has an operational mode in which triggering of any actuator within the synchronized group initiates playback of audio events or execution of control functions associated with other of the actuators within the synchronized group in one of multiple different synchronization orders, e.g. one at a time, all simultaneously, random or in a predefined or user-defined consecutive order.
