An instructional method of an electronic keyboard includes the following steps: obtaining a playing script, wherein the playing script is generated by a recording electronic keyboard; the recording electronic keyboard generates the playing script according to a pressed second key and the time of pressing the second key, and the playing script is used for indicating a corresponding relationship between a to-be-pressed key and the time of pressing the to-be-pressed key; controlling an indicator light on the first key of the instructional electronic keyboard to be turned on/off according to the playing script. In this implementation mode, a user can be prompted for the key by an indicator light on the electronic keyboard, which facilitates the user to learn the electronic keyboard.

Disclosed is an electronic device including: a display; a detector that detects contact or proximity between an operating body and a detection surface; multiple light emitters that are provided at a position corresponding to the detector, and cause the detection surface to emit light; and at least one processor. The processor performs control to link displaying regarding at least part of a content on the display with light emission of at least part of the light emitters.

An electronic musical instrument includes an input device that receives an input operation, a display, and a processor. The processor performs a first process upon duration of a detected continuation of the input operation being a reference time or longer. The processor performs a second process upon duration of a detected continuation of the input operation being less than the reference time. The processor causes the display to display a content from which it is determinable whether or not duration of a detected continuation of the input operation being the reference time or longer.

A lighting controller includes: an information acquiring unit configured to acquire music piece information including at least information on a beat position in music piece data; a lighting controller configured to control a lighting fixture with reference to a lighting-effect change point, a minimum unit of the lighting-effect change point being defined by the beat position; and an operation interlock control unit configured to apply, in response to a predetermined operation applied on a music piece reproduction apparatus configured to reproduce the music piece data as a music piece or a music piece reproduction controller configured to control the music piece reproduction apparatus, a predetermined lighting effect corresponding to the operation or a process executed by the operation to the control of the lighting fixture.

A keyboard instrument includes a processor and a keyboard including first, second and third keys. The first key is associated with first section data corresponding to a first section among a plurality of sections in a piece of music, includes at least two notes and corresponds to a first period of the piece of music. The second key is associated with second section data corresponding to a second section following the first section, includes at least two notes and corresponds to a second period of the piece of music. The third key is not associated with any section data. The processor displays an identifier such that the first and second keys are distinguishable from the third key, outputs the first section data as a musical sound when the first key is operated; and outputs the second section data as a musical sound when the second key is operated.
