A recording in visual form of a sound pattern whose tones constitute a musical composition having different and concurrent themes, which recording is formed by: A. converting the sound pattern to produce for each theme, a succession of visible solid tone bands whose lengths are proportional to the duration of the respective tones forming the theme, each band having a visual intensity which along its length is varied in accordance with the aural intensity of the tone indicated thereby, B. applying the succession of tone bands so produced to a music sheet having a grand staff defined by spaced parallel lines, the bands being placed on the staff at levels depending on their pitch, the width of each band being equal to the space between adjacent lines, and C. imparting a distinct color to each succession of tone lines whereby the themes may be distinguished from each other.
