musical mode

In music, a scale is an ordered series of musical intervals, which, along with the key or tonic, define the pitches. However, mode is usually used in the sense of scale applied only to the specific diatonic scales found below. The use of more than one mode is polymodal, such as with polymodal chromaticism. While all tonal music may technically be described as modal, music that is called modal often has less diatonic functionality and changes key less often than other music.
