Mensural notation recoverable from the modern text. While 19th and early 20th century editions of Renaissance music often preserved the large note values of the originals, including breves and longs, most modern editions will use scaled-down note values in order to match modern reading habits regarding tempo and beat structure. For 16th century music, a frequent scheme is diminution by a factor of 2 (i.e., rendering semibreves as modern minims), in a modern "alla breve" bar. Older music might be diminished by a factor of 4 (rendering semibreves as crotchets) or sometimes 8 (rendering breves as crotchets). For 13th-century pieces, diminution by
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
