Prolation Prolation Prolation is a term used in the theory of the mensural notation of medieval and Renaissance music to describe its rhythmic structure on a small scale, as opposed to "tempus", which described a larger scale. The term "prolation" is derived from the Latin "prolatio", first used by Philippe de Vitry in describing Ars Nova, a musical style that came about in 14th-century France. Prolation, together with tempus, corresponds roughly to the concept of time signature in modern music. Prolation describes whether a semibreve (whole note) is equal in length to two minims (half notes) ("minor prolation" or "imperfect prolation";
Whole tone scale Whole tone scale In music, a whole tone scale is a scale in which each note is separated from its neighbours by the interval of a whole tone. In twelve-tone equal temperament, there are only two complementary whole tone scales, both six-note or "hexatonic" scales: \override Score.TimeSignature #'stencil = ##f \relative c' { </score> \override Score.TimeSignature #'stencil = ##f \relative c' { </score> The whole tone scale has no leading tone and because all tones are the same distance apart, "no single tone stands out, [and] the scale creates a blurred, indistinct effect". This effect is especially emphasised by the
