__NOTOC__ The clavier à lumières (keyboard with lights), or ''tastiéra per luce'', as it appears in the score, was a musical instrument invented by Alexander Scriabin for use in his work ''Prometheus: Poem of Fire''. However, only one version of this instrument was constructed, for the performance of ''Prometheus: Poem of Fire'' in New York in 1915.〔 Plummer describes in detail the design and technology used to produce the instrument for the colour effect prescribed by Scriabin.〕 The instrument was supposed to be a keyboard, with notes corresponding to colors as given by Scriabin's synesthetic system, specified in the score,〔Cummings, Robert. ("Symphony No. 5 in F sharp major for piano, organ, chorus & orchestra ("Prometheus, Poem of Fire"), Op. 60" ): "in the score he specifies that certain colors should flood the concert hall during performance".〕 However, numerous synesthesia researchers have cast doubt on the claim that Scriabin was a synesthete.〔 "In fact, there is considerable doubt about the legitimacy of Scriabin's claim, or rather the claims made on his behalf, as we shall discuss in Chapter 5." (p.31-2)〕〔 "The authors conclude that the nature of Scriabin’s 'color-tonal' analogies was associative, i.e. psychological; accordingly, the existing belief that Scriabin was a distinctive, unique 'synesthete' who really saw the sounds of music—that is, literally had an ability for 'co-sensations'— is placed in doubt."〕 The "Luce" part is notated on a treble staff with two parts, one proceeding on the circle of fifths during the piece, the other following the tonal centre of the music. Scriabin assigned the following colors to the following key areas: When the notes are ordered by the circle of fifths, the colours are in order of a spectrum, which leads numerous synesthesia researchers to argue that he did not experience the physiological condition of synesthesia.〔〔〔〔 Additionally, it has been argued that Scriabin's color associations were influenced by his theosophic readings〔 and based on Sir Isaac Newton's ''Optics'' quoted by Louis Bertrand Castel:〔 "In Europe Skriabin met the painter Jean Delville, who suggested him to study the writings of Castel."〕 Scriabin was a friend of Nikolai Rimsky-Korsakov, who was also a synesthete. Scriabin's assignments of colours to keys was not the same as Rimsky-Korsakov's perceptions, which is not an indication that Scriabin was not a synesthete as all synesthetes perceive different associations. Scriabin was also heavily influenced by Theosophy, which had its own different system of associating colors and pitches (in essence going up the visible spectrum from C to B chromatically, rather than by fifths). ==See also== *Chromesthesia *Color organ *Visual music *Music visualization *New Epoch Notation Painting *List of people with synesthesia 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Clavier à lumières」の詳細全文を読む スポンサード リンク
