PIANO PRACTICE DEVICE COMPATIBLE WITH EXISTING PIANO
Technical Background
There are known devices that are mounted on keyboard instruments not including a play teaching function and guide keystroke positions.
For example, there is a known play teaching device that is mounted on a keyboard instrument and guides the playing of a keyboard. The device includes a light emitting means provided corresponding to each key of the keyboard; a keystroke instruction means for guiding keystroke by irradiating a key to be stroke with light by the light emitting means in response to a note on event of music piece data of play teaching; and a detection means for irradiating each key of the keyboard with light to detect a play state of each key by reflective light thereof.

The object of the present invention is to guide keystroke positions even without a keyboard instrument.
Means for Solving Problems
In order to achieve the above object, the disclosed practice device is provided.
This practice device includes a light source device that irradiates each keystroke position of a keyboard or a keystroke target object including keystroke positions imitating a keyboard with a light beam in different colors, fluorescent paper attached to each finger of a player in different colors for each finger, and a main device including a storage unit that stores musical piece information regarding a musical piece, and a transmission unit that transmits, to the light source device, a signal about the color of a light beam in accordance with the color attached to a finger of the player and about the lighting time of a light beam based on the music piece information stored in the storage unit.
Keystroke positions can be guided even without a keyboard instrument.
