PIANO PRACTICE DEVICE COMPATIBLE WITH EXISTING PIANO<\/strong><\/span><\/h3>\r\n

Technical Background<\/h3>\r\n

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.<\/p>\r\n

\u00a0<\/div>\r\n

Current Problems<\/strong><\/h3>\r\n

Since the above device is assumed to be mounted on a keyboard instrument, there is a problem that guiding of keystroke positions is impossible without a keyboard instrument.
The object of the present invention is to guide keystroke positions even without a keyboard instrument.<\/p>\r\n\r\n

\u00a0<\/div>\r\n\r\n

Means for Solving Problems<\/strong><\/h3>\r\n

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.<\/p>\r\n\r\n

Scope of Claims<\/strong><\/h2>\r\n

[Claim 1]<\/h4>\r\n

A practice device comprising of 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 a lighting time of a light beam based on the music piece information stored in the storage unit.<\/p>\r\n

[Claim 2]<\/h4>\r\n

The practice device according to claim 1, wherein the main device transmits a signal for irradiating a keystroke position with a light beam in the same color as the color attached to the finger matching the finger number allocated to a musical note of musical piece information.<\/p>\r\n

[Claim 3]<\/h4>\r\n

The practice device according to claim 1, further comprising of a display unit that displays a musical note of a score in the same color as the color of the color light beam on a keyboard in accordance with progress of a musical piece.<\/p>","protected":false},"excerpt":{"rendered":"PIANO PRACTICE DEVICE COMPATIBLE WITH EXISTING PIANO Technical Background There are known devices that are mou […]","protected":false},"featured_media":148,"template":"","project_category":[],"class_list":["post-55","project","type-project","status-publish","has-post-thumbnail","hentry"],"_links":{"self":[{"href":"https:\/\/www.synca-gp.co.jp\/english\/wp-json\/wp\/v2\/project\/55","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.synca-gp.co.jp\/english\/wp-json\/wp\/v2\/project"}],"about":[{"href":"https:\/\/www.synca-gp.co.jp\/english\/wp-json\/wp\/v2\/types\/project"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.synca-gp.co.jp\/english\/wp-json\/wp\/v2\/media\/148"}],"wp:attachment":[{"href":"https:\/\/www.synca-gp.co.jp\/english\/wp-json\/wp\/v2\/media?parent=55"}],"wp:term":[{"taxonomy":"project_category","embeddable":true,"href":"https:\/\/www.synca-gp.co.jp\/english\/wp-json\/wp\/v2\/project_category?post=55"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
