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.

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.

The present invention is a chromatic-emphasis hybrid-diatonic leverless keyboard configured to provide an extension, duplication, or representation of both heptatonic and pentatonic keys on the leverless keyboard. The extension enables the user to shift the physiological center of gravity for the keyboard to the area where pentatonic and heptatonic keys share space and are more isomorphic, thus assisting in gaining and applying understanding of the chromatic equality of the twelve tonalities in standard equal temperament, and in gaining and applying understanding of the one-dimensional nature of music.
