D.D. Jameson is presumed to have made, although there is no documentation of a demonstration, a device in the mid 19th century (a pamphlet was published in 1844) that he called "Colour-Music" described thus: "A pianoforte having been prepared in the manner described, any air may be slowly played. As each note is struck, its equivalent in Colour – Key, Height – Octave, Length – Time should be placed in a series on a white paper. This will be found to be of more or less pleasing character, according to the varied character of the music."
