An illustration of dithering. Red and blue are the only colors used but, as the red and blue squares are made smaller, the patch appears magenta. 256 color dithering with IrfanView. Dithering is used in computer graphics to create the illusion of color depth in images on systems with a limited color palette.
In music, timbre (/ ˈ t æ m b ər, ˈ t ɪ m-, ˈ t æ̃-/), also known as tone color or tone quality (from psychoacoustics), is the perceived sound quality of a musical note, sound or tone. Timbre distinguishes different types of sound production, such as choir voices and musical instruments.
Blue notes are used in many blues songs, in jazz, and in conventional popular songs with a "blue" feeling, such as Harold Arlen's "Stormy Weather". Blue notes are also prevalent in English folk music. [5] Bent or "blue notes", called in Ireland "long notes", play a vital part in Irish music. [6]
